Collapsar type based on initial mass and metallicity

A collapsar is a type of black hole formed inside of a massive star which spinning sufficiently fast to create a disk around the hole. [2] The model for collapsar was originally developed to explain gamma-ray burst events accompanying supernova, but the model now includes other forms. Type I collapsars form an initial neutron star but fail to supernova and after a one second delay collapse in to a black hole. Type II collapsars explode but not enough mass is ejected and the neutron star falls back into black hole. Type III collapsars collapse directly to massive black holes. [1]
