摘要：

尽管人们对公元1054年的蟹状超新星进行了多年的研究，但仍然不清楚是什么类型的事件导致了爆炸。最详细和可靠的观测光变曲线的来源记录在中国和日本的编年史中，并建议在非常明亮的初始峰值之后迅速变暗。我们将在这项工作中表明，螃蟹事件可以很好地解释了一种类型的前兆，一种现象出现在大型超新星采样和相当预期的恒星演化考虑低质量的祖先。这个非常早期的明亮瞬变之后是爆炸本身，可能是来自“小铁核”类型的低光度超新星，而不是电子捕获事件。后一个结论源于最近的模拟工作，预测电子捕获超新星将使亮度在$\sim 3$月内变得更亮，因此在白天可以看到，并且与中国的记录不匹配。

英文摘要：

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.
