failed supernova

English

Noun

failed supernova (plural failed supernovae or failed supernovas)

1. (astronomy) An event that ends the fusion lifetime of a large and massive star. It is a partial type-II supernova, where the collapse process occurs, but no significant rebound occurs, and the nascent black hole swallows the incoming implosion resulting in no outbound explosion or subsequent light burst.
