The Crab nebula and the class of Type IIn-P supernovae caused by sub-energetic electron-capture explosions
What sort of supernova (SN) gave rise to the Crab nebula? While there are several indications that the Crab arose from a sub-energetic explosion of an 8–10 M⊙ progenitor star, this would appear to conflict with the high luminosity indicated by historical observations. This paper shows that several well-known observed …
