What model describes the complete gravitational collapse required to fuel a hypernova explosion?
Answer
Collapsar model.
The immense energy release associated with a hypernova is thought to stem from a specific mechanism involving the progenitor star. This mechanism is known as the collapsar model. This model posits that the star's iron core collapses entirely under gravity so rapidly and completely that it forms a black hole almost instantaneously. This catastrophic core collapse is the fundamental driver distinguishing the physics of a hypernova from that of a standard core-collapse supernova.
