Ia型超新星的亚类和祖先起源

Type Ia Supernova Sub-classes and Progenitor Origin

Ashley J. Ruiter

摘要:

本文对Ia型超新星的起源作一简要综述。Ia型超新星爆发在峰值光度、光变曲线宽度和形状、光谱特征和宿主恒星星族环境等方面都有很大差异。仅在过去的十年里,理论模拟和观测数据已经结合在一起,严重挑战了长期存在的范式,即所有的超新星Ia都来自于大质量白矮星的爆炸。在这篇评论中,我强调了一些主要的发展(和不断变化的观点),我们的理解的性质的超新星Ia祖系统。我给一个简短的概述双星配置及其合理的爆炸机制,并从理论的角度推断一些不同的(观测分类)超新星Ia子类和它们的祖先起源之间的联系。

英文摘要:

This paper presents a short review on the current state of SN Ia progenitor origin. Type Ia supernova explosions are observed to be widely diverse in peak luminosity, lightcurve width and shape, spectral features, and host stellar population environment. In the last decade alone, theoretical simulations and observational data have come together to seriously challenge the long-standing paradigm that all SNe Ia arise from explosions of Chandrasekhar mass white dwarfs. In this review I highlight some of the major developments (and changing views) of our understanding of the nature of SN Ia progenitor systems. I give a brief overview of binary star configurations and their plausible explosion mechanisms, and infer links between some of the various (observationally-categorized) SN Ia sub-classes and their progenitor origins from a theoretical standpoint.
