Based on the results of Chen & Li (2009) and Pakmor et al. (2010), we carried out a series of binary population synthesis calculations and considered two treatment of common envelope (CE) evolution, i...
Sub-Chandrasekhar Mass Models For Type Ia Supernovae
Sub-Chandrasekhar Mass Models Type Ia Supernovae
2011/1/11
For white dwarfs accreting hydrogen or helium at rates in the range 1 to 5 x 10^(-8) Msun/yr, a variety of explosive outcomes are possible well before the star reaches the Chandrasekhar mass. The expl...

Empirically, Type Ia supernovae are the most useful, precise, and mature tools for determining
astronomical distances. Acting as calibrated candles they revealed the presence of dark energy and are b...
Hubble Space Telescope Studies of Nearby Type Ia Supernovae: The Mean Maximum Light Ultraviolet Spectrum and its Dispersion
