Photodisintegration hypernovae

Photodisintegration hypernovae is an energetic event that takes place in stars over 250 M☉. Near the end of their life, stars with this mass should undergo photodisintegration, an endothermic (energy absorbing) process which temporarily reduces pressure and temperature within the star's core. This causes the core to collapse as energy is taken away, and the collapsing core leads to the formation of a black hole that is almost as massive as the star itself. A portion of mass escapes in the form of relativistic jets, which could have "sprayed" the first metals into the universe.[1][2]
