Final fates of rotating white dwarfs and their companions in the single degenerate model of type Ia supernovae

Abstract

Taking into account the rotation of mass-accreting white dwarfs (WDs) whose masses exceed the Chandrasekhar mass, we extend our new single degenerate model for the progenitors of Type Ia supernovae (SNe Ia), accounting for two types of binary systems: those with a main-sequence companion and those with a red-giant (RG) companion. We present a mass distribution of WDs exploding as SNe Ia, where the WD mass ranges from 1.38 to 2.3 M ⊙. These progenitor models are assigned to various types of SNe Ia. A lower mass range of WDs (1.38 M ⊙
