Document Summary
For a type i (carbon-detonation) supernova, it unlikely that anything is left behind after the explosion. The entire star is shattered by the blast. For a type ii (core-collapse) supernova, part of the star survives the explosion. Iron core of a massive star collapses until its neutrons effectively come into contact with one another. At that point, central portion of the core rebounds, creating a powerful shock wave that races outward through the star, violently expelling matter into space. *shock wave does not start at the very centre of the collapsing core* The innermost part of the core (which rebounds) remains intact as the shock wave it produces destroys the rest of the star. Neutron star - an ultracompressed ball of neutrons that remains after a type ii supernova has subsided. Average density can reach 107 or even 108 kg/m3; nearly a billion tomes denser than a white dwarf.
