A Supersymmetric model for triggering Supernova Ia in isolated white dwarfs
Supersymmetric model Supernova Ia
font style='font-size:12px;'>
2010/11/11
In a two parameter phase transition model we fit the rate and several properties of type I super-novae and address the gap in the supermassive black hole mass distribution. One parameter is a critical...
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...
Classification of field dwarfs and giants in RAVE and its use in stellar stream detection
Galaxy Astrophysics (astro-ph.GA)

An efficient separation between dwarfs and giants in surveys of bright stars is important, especially for studies in which distances are estimated through photometric parallax relations.
The formation of high-field magnetic white dwarfs from common envelopes
Solar and Stellar Astrophysics (astro-ph.SR)
font style='font-size:12px;'>
2010/12/27
The origin of highly-magnetized white dwarfs has remained a mystery since their initial discovery. Recent observations indicate that the formation of high-field magnetic white dwarfs is intimately rel...
A Census of White Dwarfs Within 40 Parsecs of the Sun
Solar and Stellar Astrophysics (astro-ph.SR)
font style='font-size:12px;'>
2010/12/27
Our aim is to compile a catalog of white dwarfs within 40 parsecs of the Sun, in which newly discovered objects would significantly increase the completeness of the current census. White dwarf candida...
