astrophysics - What is the process that causes a collapsing star to bounce back?



Can someone explain the process by where a star collapses and bounces back. I haven't been able to find a good explanation of the bounce. Edit here, I was wondering specifically where the energy of the bounce comes from. It seems like the mass must decrease in proportion, or the energy must have beens stored some other way. I guess the mechanism is not completely understood, or I would ask that question.
