一颗双星可能拥有复发的热核超新星

A Single Binary May Host Recurrent Thermonuclear Supernovae

Kaela J. Lee, Ken J. Shen

摘要:

Iax型超新星(SNe Iax)最普遍被接受的前身系统是一颗质量接近600亿塞卡的白矮星(WD)从一颗非简并的氦供体恒星吸积而产生的部分爆燃,爆炸后留下一个束缚的残余物。在本文中,我们调查WD残留是否可以在系统的生命周期中经历多个SNe。我们使用模块在天体物理学实验(MESA)发展各种单简并双星,以确定可能会经历多个SNe Iax由于多个氦吸积阶段。我们还调查了双WD系统形成后,随后的Ia型SN的可能性。我们的工作的结论是,相对高质量的捐助者密切的双星产生的几个热核SNe的概率最高。

英文摘要:

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