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...
Abundance Patterns in S-type AGB stars : Setting Constraints on Nucleosynthesis and Stellar Evolution Models
Abundance Patterns Setting Constraints Stellar Evolution Models
2010/11/12
During the evolution on the AGB, S-type stars are the first objects to experience s-process nucleosynthesis and third dredge-ups, and therefore to exhibit sprocess signatures in their atmospheres.
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 stellar evolution of Luminous Red Galaxies, and its dependence on colour, redshift, luminosity and modelling
galaxies evolution - cosmology observations - surveys
2010/11/15
We present a series of colour evolution models for Luminous Red Galaxies (LRGs) in the 7th spectroscopic data release of the Sloan Digital Sky Survey (SDSS), computed using the full-spectrum fitting c...
Review about populations of Be stars: stellar evolution of extreme stars
Solar and Stellar Astrophysics (astro-ph.SR)
2011/1/6
Among the emission-line stars, the classical Be stars known for their extreme properties are remarkable. The Be stars are B-type main sequence stars that have displayed at least once in their life emi...
