failed supernova
English
Etymology
failed + supernova From the lack of a light burst at the end of a star's life, being an incomplete supernova, where the implosion occurs without the explosion that lights up the universe, failing to become a bright (super) 'new "star"' (nova)
Noun
failed supernova (plural failed supernovae or failed supernovas)
- (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.
