论文摘要
尽管多年来研究了公元1054年的螃蟹超新星,但仍不清楚发生了什么类型的爆炸事件。观测到的光曲线的最详细和可靠的来源记录在中国和日本编年史中,并在非常明亮的初始峰后快速变暗。我们将在这项工作中表明,螃蟹事件可以通过一种类型的前体来很好地解释,这种现象来自大型超新星采样,也可以从低质量祖细胞的恒星进化考虑方面进行。这种非常早的明亮瞬态之后是爆炸本身,可能是``小铁核心''类型的低亮度超新星,而不是电子捕获事件。后一个结论源于最近的模拟工作,该工作预测电子捕获超新星将使$ \ sim 3 $ 3 $ $ \ sim的幅度更明亮,因此在白天可见,并且与中国的记录不符。
In spite that the Crab supernova in 1054 A.D. was studied over the years, it is still not clear what type of event produced the explosion. The most detailed and reliable source of the observed light curve is recorded in the Chinese and Japanese chronicles, and suggests a quick dimming after a very bright initial peak. We shall show in this work that the Crab event can be well explained by a type of precursor, a phenomenon emerging from large supernova sampling and quite expected from Stellar Evolution considerations of low-mass progenitors. This very early bright transient is followed by the explosion itself, likely a low-luminosity supernova from ``small iron core'' type instead of an electron-capture event. The latter conclusion stems from recent simulation work, which predict that an electron-capture supernova would render the magnitude to be much brighter for $\sim 3$ months, hence visible during daytime, and would not match the Chinese records.
