Distribution and Origin of Hot Planets
C. Beauge
1
Close-in (or Hot) planets, usually defined as those having semimajor axes a < 0.1 AU (or orbital periods
P < 10 days), are the easiest to detect, both with radial velocity (RV) surveys and transits. More than 300
members are currently known, and a much larger number of candidates has been proposed by the Kepler
team. Since it is believed that these bodies cannot have been formed in-situ, they constitute an interesting
population from which to derive information about orbital migration and dynamical evolution of planetary
systems in general.
In this talk we review some recent results on the dynamical characteristics of close-in planets, including the
existence of both resonant and near-resonant configurations, planet multiplicity, eccentricity distribution
and inclinations with respect to the stellar equator. We discuss how disk-induced migration, planet-planet
scattering and tidal effects may help us explain several of these dynamical traits, although others are still
poorly understood. Finally, we analyze the similarities and differences found in small (Earth to Neptune)
and large (Jovian) size planets, and how these may reflect different evolutionary histories.

Impact studies in Latin America
Gonzalo Tancredi
1
The research about impact process of extraterrestrial bodies onto the Earth is a new subject in only a few
institutes in Latin America. A proof of that is the scarcity of recognized impact structures in the region. Nevertheless, we have among the most interesting features on Earth, like the crater strewn fields of Campo del
Cielo (Chaco, Argentina) and Bajada del Diablo (Neuquén, Argentina); and the recently formed small crater
of Carancas (Perú). These cases have questioned several ideas about the nature of the impacting objects:
monolithic vs. agglomerate; as well as the survival of the objects in the passage through the atmosphere.
These questions have important implications regarding the plans to deflect a threatening asteroid and the
risk and consequences of small impactors. A few groups in the region have been involved in field research in
those craters, as well as experimental and theoretical studies about impact processes and deflection mechanisms. We will highlight the most relevant results on this growing scientific field.

Supergiants, Stellar Winds and Mass-loss
Cidale, L.
1,2
The knowledge of the wind properties and the mass loss rate in massive stars is a milestone in the stellar
evolution and the chemical composition of the interestellar medium. Our current view of stellar winds
reveals they are often highly variable and inhomogeneous. We review here the wind structure of early-type
stars (the wind clumping and the weak-wind problems) and the peculiar circumstellar environment around
some short-lived phases of evolved massive stars (i.e.: LBVs and B[e] supergiants). Accurate mass loss rate
estimates are crucial keys to discuss the importance of different triggering mechanisms in driving the wind.

Abundance determinations in ionized nebulae and their sensitivity to temperature
Rodriguez, M.
1
; Manso-Sainz, R.2
Our main source of uncertainty in the determination of chemical abundances in H II regions and planetary
nebulae arises from a discrepancy: the abundances implied by recombination lines are larger than those
implied by collisionally excited lines. Most objects show a factor of 2 discrepancy, but some planetary nebulae display much higher discrepancies. I will discuss the possible explanations of this effect, focusing on
the latest: I will describe what kind of deviations from a Maxwellian electron energy distribution are needed
in order to reproduce the measured abundance discrepancies. I will explore the parallelisms between the
three explanations of the discrepancy that are based on the sensitivity to temperature of collisionally excited lines, namely, deviations from a Maxwellian energy distribution, temperature fluctuations, and the
presence of metal-rich inclusions. I will show some evidence that at least one of these mechanisms is acting
in H II regions.

Solar Transient Activity: Magnetic Energy Release and Topology
Mandrini, C. H.
1
The energy released during transient atmospheric events in the Sun is contained in current-carrying magnetic fields that have emerged after traversing the solar convective zone. Once the magnetic flux reaches
the photosphere, it may be further stressed via motions in this lower atmospheric layer. Magnetic field
reconnection is thought to be the mechanism through which the stored magnetic energy is transformed
into kinetic energy of accelerated particles and mass flows, and radiative energy along the whole electromagnetic spectrum. Though this mechanism is efficient only at very small spatial scales, it may imply a
large-scale restructuring of the magnetic field which is inferred from the combined analysis of observations, models of the coronal magnetic field, and computation of its topology. The consequences of energy
release include events that range from nano-flares, still below our present observational spatial resolution,
to powerful flares that may be accompanied by the ejection of large amounts of plasma and magnetic field
in events called coronal mass ejections (CMEs). We will review key observational signatures of flares and
CMEs on the Sun and discuss how the computation and analysis of the magnetic field topology, applied to
the widest variety of observed magnetic configurations, can be used to identify the energy release locations
and their physical characteristics.

The SNC Meteorites
Varela, M. E.
1
The SNC (Shergotty-Nakhla-Chassigny) group, are achondritic meteorites. Of all SNC meteorites recognized
up to date, shergottites are the most abundant group. The petrographic study of Shergotty began several
years ago when Tschermak, (1872) identified this rock as an extraterrestrial basalt. Oxygen isotopes in SNC
meteorites indicate that these rocks are from a single planetary body (Clayton and Mayeda, 1983). Because
the abundance patterns of rare gases trapped in glasses from shock melts (e.g., Pepin, 1985) turned out
to be very similar to the Martian atmosphere (as analyzed by the Viking landers, Owen, 1976), the SNC
meteorites are believed to originate from Mars (e.g. McSween, 1994). Possibly, they were ejected from the
Martian surface either in a giant impact or in several impact events (Meyer 2006). Although there is a broad
consensus for nakhlites and chassignites being -1.3Ga old, the age of the shergottites is a matter of ongoing
debates. Different lines of evidences indicate that these rocks are young (180Ma and 330-475Ma), or very old
(> 4Ga). However, the young age in shergottites could be the result of a resetting of these chronometers by
either strong impacts or fluid percolation on these rocks (Bouvier et al., 2005-2009). Thus, it is important to
check the presence of secondary processes, such as re-equilibration or pressure-induce metamorphism (El
Goresy et al., 2013) that can produce major changes in compositions and obscure the primary information.
A useful tool, that is used to reconstruct the condition prevailing during the formation of early phases or
the secondary processes to which the rock was exposed, is the study of glass-bearing inclusions hosted by
different mineral phases. I will discuss the identification of extreme compositional variations in many of
these inclusions (Varela et al 2007-2013) that constrain the assumption that these objects are the result of
closed-system crystallization. The question then arises whether these inclusions can be considered reliable
samples of the fluid/melt that was originally trapped.5

New Opportunities with the Gemini Observatory
M. Boccas
1
Gemini Observatory’s associate director for development Maxime Boccas will present an update of the facility and introduce some new opportunities for astronomers at Gemini. Gemini operates twin 8-m telescopes,
one in Hawaii and the other in Chile. The departure of the UK from Gemini’s international partnership at
the end of 2012 provided the chance to re-evaluate the services offered to Gemini users and opened new
opportunities in two domains. First, Gemini will welcome discussions with groups wanting to bring their
own instruments for campaigns. This visiting instrument program will complement the suite of workhorse
instruments offered by the Observatory, and will allow scientific breakthroughs not possible with the regular suite of instruments. Second, the Gemini observatory will be offering cross-partnership large or long
programs. From 2014 on, Gemini will be dedicating 20collaborative programs selected through a yearly
call. Gemini is also looking at the possibility of offering some fraction of time in a fast turn-around mode,
as well as ”eavesdropping” for queue observing. We remain very interested in having astronomers visit
the telescopes. In addition to these two major initiatives, several new instruments have appeared in 2013:
Flamingos-2 and the Gemini Multi-conjugate adaptive optics System (GeMS) are being offered for science,
and the Gemini Planet Imager (GPI) has arrived on Cerro Pachon.

Active Galactic Nuclei
Arévalo, P.
1
Accreting supermassive black holes have had a large impact in the evolution of their host galaxies, and even
inject significant energy into their host cluster of galaxies. Although the black hole’s influence in these large
structures is evident, the central engine itself is remarkably difficult to observe. Their extremely compact
nature makes it impossible to resolve the final source of fueling, the accretion disc, although interferometric
observations have started to reveal important details of the material directly outside this region. In this talk
I will review the techniques that have shed light into the structure and behavior of these central engines in
the quest to find out how black hole grow.

Diversity of protoplanetary disks in stellar clusters: the case of the sigma Orionis
cluster

The
Orionis cluster is a natural laboratory to study stars and protoplanetary disks in the first stages of
their evolution. This cluster is relatively near (Distance
400 pc) and the extinction is low (AV < 0.5 mag)
and thus enable us to study young stars in a entire range of masses, from its most massive star (O9.5 type
star) to the lowest mass objects, such as brown dwarfs and free-floating planets. Recently, we have obtained
the largest and most homogeneous spectroscopic characterization to date of stars belong to this cluster.
This information is a corner stone to derive stellar parameter. Of particular interest are stars that exhibit
infrared excesses produced by protoplanetary disks. Since the Orionis cluster has an evolutionary stage
in which mechanisms of disk dispersal have affected substantially its disk population, we observe large
diversity of disks in this stellar cluster (e.g.,optically thick full disks, pre-transitional disks, transitional disks,
homogeneusly depleted disks and debris disks). More than 100 stars bearing protoplanetary disks have
been detected in the
Orionis cluster with the disk census presented few years ago using IRAC and MIPS
observations. In this contribution, we present an overview of the latest results of an ongoing study of the
disk population in the
Orionis cluster combining Hershel-PACS observation, IRS spectroscopic data for
selected targets and theoretical models of disk evolution. In order to get a better understand of how disk
evolves from optically thick full disks to debris disks, these results will be combined with similar studies that
we are doing in more dispersed and older regions of the Orion OB1a and OB1b sub association.

White Dwarf Stars
S. O. Kepler
1
White dwarfs are the evolutionary endpoint for nearly 95% of all stars born in our Galaxy, the final stages of
evolution of all low- and intermediate mass stars, i.e., main sequence stars with masses below (8.5±1.5) M ,
depending on metallicity of the progenitor, mass loss and core overshoot. Massive white dwarfs are intrinsically rare objects, tand produce a gap in the determination of the initial vs. final mass relation at the high
mass end (e.g. Weidemann 2000 A&A, 363, 647; Kalirai et al. 2008, ApJ, 676, 594; Williams, Bolte & Koester
2009, ApJ, 693, 355). Main sequences stars with higher masses will explode as SNII (Smartt S. 2009 ARA&A,
47, 63), but the limit does depend on the metallicity of the progenitor. Massive white dwarfs are probably
SNIa progenitors through accretion or merger. They are rare, being the final product of massive stars (less
common) and have smaller radius (less luminous). Kepler et al. 2007 (MNRAS, 375, 1315), Kleinman et al.
2013 (ApJS, 204, 5) estimate only 1-2% white dwarfs have masses above 1 M . The final stages of evolution after helium burning are a race between core growth and loss of the H-rich envelope in a stellar wind.
When the burning shell is exposed, the star rapidly cools and burning ceases, leaving a white dwarf. As
they cool down, the magnetic field freezes in, ranging from a few kilogauss to a gigagauss. Peculiar type
Ia SN 2006gz, SN 2007if, SN 2009dc, SN 2003fg suggest progenitors in the range 2.4 2.8 M , and Das U.
& Mukhopadhyay B. (2012, Phys. Rev. D, 86, 042001) estimate that the Chandrasekhar limit increases to
2.3
2.6 M for extremely high magnetic field stars, but differential rotation induced by accretion could
also increase it, according to Hachisu I. et al. 2012 (ApJ, 744, 69). Garcı́a-Berro et al. 2012, ApJ, 749, 25,
for example, proposes double degenerate mergers are the progenitors of high-field magnetic white dwarfs.
We propose magnetic fields enhance the line broadening in WDs, causing an overestimated surface gravity,
and ultimately determine if these magnetic fields are likely developed through the star’s own surface convection zone, or inherited from massive Ap/Bp progenitors. We discovered around 20 000 spectroscopic white
dwarfs with the Sloan Digital Sky Survey (SDSS), with a corresponding increase in relatively rare varieties of
white dwarfs, including the massive ones (Kleinman et al. 2013, ApJS, 204, 5, Kepler et al. 2013, MNRAS,
439, 2934). The mass distributions of the hydrogen-rich (DA) measured from fitting the spectra with model
atmospheres calculated using unidimensinal mixing lenght-theory (MLT) shows the average mass (as measured by the surface gravity) increases apparently below 13 000K for DAs (e.g. Bergeron et al. 1991, ApJ, 367,
253; Tremblay et al. 2011, ApJ, 730, 128; Kleinman et al. 2013). Only with the tridimensional (3D) convection
calculations of Tremblay et al. 2011 (A&A, 531, L19) and 2013 (A&A, 552, 13; A&A, 557, 7; arXiv 1309.0886) the
problem has finally been solved, but the effects of magnetic fields are not included yet in the mass determinations. Pulsating white dwarf stars are used to measure their interior and envelope properties through
seismology, and together with the luminosity function of white dwarf stars in clusters and around the Sun
are valuable tools for the study of high density physics, and the history of stellar formation.

The evolution of protoplanetary disk
Matthias R. Schreiber
1
The evolution of protoplanetary disks is essential for the star and planet formation process. While we have
discovered several mechanisms that are likely to drive the evolution of disks, e.g. grain growth, photoevaporation, planet formation, or binarity, we still struggle to understand their relative importance for the global
evolution of protoplantary disks and to relate them to observations. I will review recent progress based on
large infrared surveys of star forming regions, highlight spectacular discoveries made with ALMA, discuss
the possible detections of forming planets still embedded in their disks, and outline the future prospects of
this rapidly advancing research field.

Galaxies at High Redshift
Franz. E. Bauer
1
Recent years have seen tremendous progress in finding and charactering star-forming galaxies at high redshifts across the electromagnetic spectrum, giving us a more complete picture of how galaxies evolve, both
in terms of their stellar and gas content, as well as the growth of their central supermassive black holes. A
wealth of studies now demonstrate that star formation peaked at roughly half the age of the Universe and
drops precariously as we look back to very early times, and that their central monsters apparently growth
with them. At the highest-redshifts, we are pushing the boundaries via deep surveys at optical, X-ray, radio
wavelengths, and more recently using gamma-ray bursts. I will review some of our accomplishments and
failures.
Telescope have enabled Lyman break galaxies to be robustly identified, but the UV luminosity function
and star formation rate density of this population at z = 6
8 seems to be much lower than at z = 2
4.
High escape fractions and a large contribution from faint galaxies below our current detection limits would
be required for star-forming galaxies to reionize the Universe. We have also found that these galaxies have
blue rest-frame UV colours, which might indicate lower dust extinction at z > 5. There has been some
spectroscopic confirmation of these Lyman break galaxies through Lyman- emission, but the fraction of
galaxies where we see this line drops at z > 7, perhaps due to the onset of the Gunn-Peterson effect (where
the IGM is opaque to Lyman- ).

The spatially resolved star formation history (SFH) of galaxies contains fundamental information to understand how the galaxies formed and evolve. We apply the fossil record method based on spectral synthesis
techniques to recover the SFH resolved in space and time for more than 200 galaxies from the CALIFA survey, which is gathering Integral Field Spectroscopy over the optical range and up to radial distances of 3 half
light radii (HLR) of local (z = 0.005–0.03) galaxies. This CALIFA sub-sample is well distributed in the colormagnitude diagram and contains a fair representation from the ellipticals through the bulge dominated to
the pure disk galaxies. In terms of stellar mass, the galaxies are distributed between Log M (Msun)= 9 to 12
with a peak in galaxies like the MW and M31. We investigate the SFH of galaxies and their trends of the radial
structure as a function of the galaxy stellar mass and morphology. We show how the different galactic spatial
sub-components (”bulge” and ”disk”) grow their stellar mass over time. We find that star formation history
of bulges is more fundamentally related to the stellar galaxy mass, and in contrast disks is related with the
local stellar mass surface density. We also obtain the spatially averaged and integrated galaxy properties,
and how they are related with the properties at 1HLR.

ESO: Present and Future
Andreas Kaufer

ESO is an intergovernmental organization for astronomy founded in 1962 by five countries. It currently has
14 Member States in Europe with Brazil poised to join as soon as the Accession Agreement has been ratified. Together these countries represent approximately 30 percent of the world’s astronomers. ESO operates
optical/infrared observatories on La Silla and Paranal in Chile, partners in the sub-millimeter radio observatories APEX and ALMA on Chajnantor and is about to start construction of the Extremely Large Telescope
on Armazones.
La Silla hosts various robotic telescopes and experiments as well as the NTT and the 3.6m telescope. The
former had a key role in the discovery of the accelerating expansion of the Universe and the latter hosts
the ultra-stable spectrograph HARPS which is responsible for the discovery of nearly two-thirds of all confirmed exoplanets with masses below that of Neptune. On Paranal the four 8.2m units of the Very Large
Telescope, the Interferometer and the survey telescopes VISTA and VST together constitute an integrated
system which supports 16 powerful facility instruments, including adaptive-optics-assisted imagers and
integral-field spectrographs, with half a dozen more on the way and the Extremely Large Telescope with its
suite of instruments to be added in about ten years time. Scientific highlights include the characterisation
of the supermassive black hole in the Galactic Centre, the first image of an exoplanet, studies of gamma-ray
bursts enabled by the Rapid Response Mode and milliarcsec imaging of evolved stars and active galactic
nuclei. The single dish APEX antenna, equipped with spectrometers and wide-field cameras, contributes
strongly to the study of high-redshift galaxies and of star- and planet-formation. Early Science results obtained with the ALMA interferometer already demonstrate its tremendous potential for observations of the
22
cold Universe.
The review will summarize the entire ESO program and consider the next steps.

Determining the distances of the structures surrounding super-massive black holes
Steenbrugge, K. C.
1,2
The surroundings of super-massive black holes located in the centers of active galaxies is complex with
many components, such as the accretion disk, the corona, broad line region, the reflection component,
the torus and warm absorber, which is outflowing ionized plasma. The distance from the black hole, the
size and geometry of most of these components is poorly constrained. To constrain some of these physical
parameters we used the technique of time-resolved UV and X-ray spectroscopy. We obtained optical to
gamma-ray spectra and lightcurves over 100 days for Mrk 509, one of the brightest AGN in the X-ray band.
The most important conclusions are that the corona is consistent with an optically thick and relatively low
temperature layer on top of the accretion disk, compto-ionizing the accretion disk photons. The reflection
component, easily detected through the broad Fe K line, is located between 40-1000 gravitational radii
from the black hole. Two of the warm absorber components have a distance of
10 pc and for the others
the distance is larger than 70 pc, and all are thus located well outside the broad line region. From these
distances we can constrain the importance of these outflows on galactic evolution through feedback and
the recycling of metals in the galaxy.

Testing Fundamental Hypotheses in Cosmology
J. S. Alcaniz
1
Testing fundamental hypotheses in cosmology constitutes an important task for fundamental physics since
any violation of them would be a clear evidence of new physics. In this talk, we review some of these hypotheses and discuss the possibility of testing the so-called cosmic distance duality relation (CDDR). We
derive a new relation involving current measurements of the gas mass fraction of galaxy clusters from the
Sunyaev-Zeldovich effect fSZE and x-ray surface brightness fX
where
ray
observations, i.e., fSZE =
fX
ray ,
quantifies deviations from the CDDR. Since this latter expression is valid for the same object in
a given galaxy cluster sample, its application to current data removes possible contaminations from different systematics error sources and redshift differences involved in luminosity and angular diameter distance
measurements. We use the most recent fX
ray
and fSZE data to test the CDDR as an exact principle in
Nature and discuss the results in the light of some possible physics mechanisms of CDDR violation.

Multiple-tracer surveys of the large-scale structure of the Universe
1
L. Raul Abramo
New astrophysical surveys are starting to detect galaxies of many different types in massive numbers. At the
same time, these surveys are also mapping with exquisite accuracy the different environments where these
galaxies live. I will show that redshift surveys that map several different tracers of large-scale structure (e.g.,
galaxies of different luminosities, or halos of different masses) are a new leap forward for Cosmology. These
surveys can even appear to overcome the fundamental statistical limitation known as cosmic variance. I
will show how this is in fact possible, and how we can enhance constraints on cosmological parameters
when a given survey has a sufficient number of tracers of large-scale structure of different biases. I will
make the case for the multiple-tracer approach using the concrete example of J-PAS (the Javalambre PAU
Astrophysical Survey), one of the most promising redshift surveys of the near future.

Millimetron is a 10-meter cooled space observatory that is optimized for the far-infrared and submm wavelength range. The facility has two operating modes: one can operate as a single-dish observatory or as an
element of a space-earth VLBI system. It will have scientific capabilities that can address various key problems in astronomy and astrophysics such as the formation and evolution of stars and planetary systems,
evolution of galaxies, quasars etc.. The telescope will be deployed in space and the panels of the primary
mirror are to be adjustable to achieve an rms accuracy less than 10 micron. The telescope and instrument
compartment will be cooled down to 4.5K by passive cooling and mechanical coolers. The instrument package is to include a set of heterodyne receivers operating in several bands between from 500 and 5000 GHz,
a submm array camera/spectrometer and a mm array camera/spectrometer covering 50 micron to 3 mm.
10is to include a wide international collaboration. CurMillimetron is proposed as a Russian-led mission and
rently, the mission scheduled to be launched in 2020.

The SOFIA Airborne Infrared Observatory - first science highlights and future science
potential
Hans Zinnecker
1
SOFIA, short for Stratospheric Observatory for Infrared Astronomy, is a Boeing 747SP aircraft with a 2.7m
telescope flying as high as 45000 ft in the stratosphere above 99 percent of the precipitable water vapor.
SOFIA normally operates from its base in Palmdale, California, and a typical observing flight lasts for 10
hours before returning to base.
SOFIA has started astronomical observations in Dec 2010 and has completed some 30 early science
flights in 2011, delivering a number of exciting results and discoveries, both in mid-infrared imaging (540mu) and in far-infrared (THz) heterodyne high-resolution spectroscopy which were published in mid2012 in special issues of ApJ Letters and A & A, respectively. Meanwhile, in July 2013, as part of Cycle 1,
SOFIA has deployed to New Zealand for a total of 9 flights (all of them successful) and has observed key targets in the southern hemisphere at THz frequencies, including star forming regions in the Large and Small
Magellanic Clouds.
In this talk, I will present a few highlights of SOFIA early science and its future potential, when the full
suite of 7 instruments will be implemented by the time of full operations in 2015. As Herschel ran out of
cryogens in April 2013, SOFIA will be the premier FIR-astronomical facility for many years to come. Synergies with ALMA and CCAT must be explored.
SOFIA is a major bilateral project between NASA and the German Space Agency (DLR), however as an
international observatory it offers observing time to the whole astronomical community world-wide, not
only to the US and German primary partners.

Star formation
Star and planet formation in the era of the submillimeter observatories SMA/ALMA
Luis Zapata

In this talk, I will present the recent advances and challenges on the star and planet formation studies in
era of the submillimeter observatories: the Submillimeter Array (SMA) and the Atacama Large Millimeter/Submillimeter Array (ALMA). These observatories now provide angular resolutions similar to those obtained in the optical regimen allowing to study the obscured innermost parts of the circumstellar disks
where the planet and star formation are taken place. When ALMA is finished, its sensivity and high angular resolution might reveal planets around close-by young stars just in the process of formation. This will
open a new venue for the understanding on the origin of our own solar system.
