论文摘要

巨大的恒星朝着其最内在的核心灾难性崩溃发展,从而产生了核心爆发的超新星(SN)爆炸作为最终产物。白矮人是通过巨大恒星的进化而形成的,如果在二进制演化过程中满足了某些条件,也会爆炸为热核SNE。现在,瞬态观察中的机会膨胀提供了大量的数据,我们开始解决恒星进化和SN爆炸机制中各种未解决的问题。在本章中,我们概述了朝向SNE的恒星进化通道,不同类型的爆炸机制以及爆炸性的核合成。然后,我们总结了SNE的观察性质,可以限制祖细胞和爆炸机制的本质。

Massive stars evolve toward the catastrophic collapse of their innermost core, producing core-collapse supernova (SN) explosions as the end products. White dwarfs, formed through evolution of the less massive stars, also explode as thermonuclear SNe if certain conditions are met during the binary evolution. Inflating opportunities in transient observations now provide an abundance of data, with which we start addressing various unresolved problems in stellar evolution and SN explosion mechanisms. In this chapter, we overview the stellar evolution channels toward SNe, explosion mechanisms of different types, and explosive nucleosynthesis. We then summarize observational properties of SNe through which the natures of the progenitors and explosion mechanisms can be constrained.
