Helium double-detonation explosions for the progenitors of type Ia supernovae

摘要

Thermonuclear explosions from helium double-detonation sub-Chandrasekhar mass model have been considered as an alternative way for the production of type Ia supernovae (SNe Ia). In this work, we systematically studied the helium double-detonation model, in which a carbon-oxygen white dwarf (CO WD) accumulates a helium layer from a non-degenerate helium star.
