论文摘要
本文对SN IA祖细胞起源的当前状态进行了简短的评论。 IA型超新星爆炸被观察到峰值光度，灯光宽度和形状，光谱特征和宿主恒星种群环境的广泛多样。仅在过去的十年中，理论模拟和观察数据就会汇集在一起，严重挑战了所有Sne IA的长期范式，这些范式均来自Chandrasekhar Mass White Dwarfs的爆炸。在这篇评论中，我强调了我们对SN IA祖细胞系统本质的理解的一些主要发展（以及改变的观点）。我简要概述了二进制恒星配置及其合理的爆炸机制，并从理论的角度来推断出各种（观察分类的）SN IA子类别（观察分类）SN IA子类及其祖细胞起源之间的联系。
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.
