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...
Fundamental Properties of the Highly Ionized Plasmas in the Milky Way
Galaxy disk — ISM Clouds — ISM structure — ultraviolet ISM
2010/11/15
The cooling transition temperature gas in the interstellar medium (ISM), traced by the high ions,Si IV, C IV, N V and O VI, helps to constrain the flow of energy from the hot ISM with T > 106 K to the...
Chemically Peculiar A/F Stars in Open Clusters of the Milky Way
stars: abundances - stars main sequence - stars rotation - diffusion - Galaxy
2010/11/12
Abundance anomalies have been determined at the surface of many field and open cluster A
and F dwarfs. These abundance anomalies are most likely caused by microscopic diffusion at work within the sta...
We present a brief history of Galactic astrophysics, and explain the origin of halo substructure in the Galaxy. We motivate our study of tidal streams by highlighting the tight constraints that analys...
