A Single Binary May Host Recurrent Thermonuclear Supernovae

摘要
The most commonly accepted progenitor system for Type Iax supernovae (SNeIax) is the partial deflagration of a near-Chandrasekhar-mass white dwarf (WD)accreting from a non-degenerate helium donor star, leaving a bound remnantfollowing the explosion. In this paper, we investigate whether the WD remantcan undergo multiple SNe during the system's lifetime. We use Modules forExperiments in Astrophysics (MESA) to evolve various single-degenerate binariesto determine which could plausibly undergo multiple SNe Iax due to multiplehelium accretion phases. We also investigate the possibility for a subsequentType Ia SN after the formation of a double WD system. Our work concludes thatclose binaries with relatively high-mass donors produce the highest probabilityfor several thermonuclear SNe.
