Extrapolating the Evolution of Galaxy Sizes to the Epoch of Reionization
galaxies evolution formation high-redshift cosmology theory
2010/11/16
We use data on the high-redshift evolution of the size distribution and luminosity function of galaxies to constrain the relationship between their star formation eciency and starburst lifetime. Base...
Catalogs of Hot White Dwarfs in the Milky Way from GALEX's Ultraviolet Sky Surveys. Constraining Stellar Evolution
Astronomical Data Bases catalogues — stars white dwarfs — stars evolution — Galaxy
2010/11/11
We present comprehensive catalogs of hot star candidates in the Milky Way, se-lected from GALEX far-UV (FUV, 1344-1786°A) and near-UV (NUV, 1771-2831°A)imaging. The FUV and NUV photometry allows us to...
Origin and Dynamical Evolution of Neptune Trojans - II: Long Term Evolution
Kuiper Belt celestial mechanics minor planets asteroids – Solar system
2010/11/10
Following our earlier work studying the formation of the Neptunian Trojan population during the
planet’s migration, we present results examining the eventual fate of the Trojan clouds produced in tha...
Low-ionization galaxies and evolution in a pilot survey up to z = 1
cosmology observations galaxies: evolution large scale structures evolution
2010/11/12
We present galaxy spectroscopic data on a pencil beam of 10.75′ × 7.5′ centered on the X-ray cluster RXJ0054.0-2823 at z = 0.29. We study the spectral evolution of galaxies from z = 1 down to the clus...
Abundance anomalies in pre-main-sequence stars: Stellar evolution models with mass loss
Diffusion — stars chemically peculiar — stars mass–loss — stars pre–main-sequence — stars evolution — stars
2010/11/12
Aims. The effects of atomic diffusion on internal and surface abundances of A and F pre–main-sequence stars with mass loss are studied in order to determine at what age the effects materialize, as wel...
The evolution of stellar structures in dwarf galaxies
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/28
We present a study of the variation of spatial structure of stellar populations within dwarf galaxies as a function of the population age. We use deep Hubble Space Telescope/Advanced Camera for Survey...
On the evolution of intra-cluster gas within Galactic globular clusters
Solar and Stellar Astrophysics (astro-ph.SR) Galaxy Astrophysics (astro-ph.GA)
2010/12/27
It has been known since the 1950's that the observed gas content of Galactic globular clusters (GCs) is 2-3 orders of magnitude less than the mass lost by stars between Galactic disk crossings.

My life is like a Babel tower: it is spread among severals european countries, France, Spain and Portugal. My acknowledgments cannot thus escape to be multi-language.
