The collapse may bring about violent expulsion of the outer layers on the star resulting in a supernova. Having said that, if the discharge of gravitational potential Vitality is inadequate, the star could rather collapse right into a black gap or neutron star with minimal radiated energy.[102]

The atypical subluminous Sort II SN 1997D Stars with Original masses a lot less than about 8 M☉ in no way produce a Main big more than enough to collapse they usually sooner or later reduce their atmospheres to be white dwarfs. Stars with at least nine M☉ (potentially just as much as twelve M☉[116]) evolve in a posh fashion, progressively burning heavier features at hotter temperatures inside their cores.
