What is the designated final remnant left behind after a hypernova's core undergoes complete gravitational collapse?
Answer
A stellar-mass black hole.
The ultimate fate of the progenitor core during a hypernova event is defined by its complete collapse. Unlike standard core-collapse events where the core might halt at the neutron star stage, the hypernova scenario involves the core imploding so thoroughly that it immediately forms a black hole. This resulting stellar-mass black hole becomes the central engine that drives the accretion disk and launches the relativistic jets responsible for the explosion's observable features.
