Ok, although that doesn'tmake a lot of sense to me, I will buy that. However, where is the white dwarf? After the supernova, wouldn't it continue to interact within the same gravitational system? The original body wouldn't have simply vaporized. Something would have to have been leftbehind, right?
Type II Supernovae
Unlike type I supernovae, type II supernovae are the result of an isolated star reaching the end of its life. Whereas stars like our Sun will eventually lack enough energy in their cores to sustain fusion past carbon, larger stars -- more than 8 times the mass of our Sun -- will eventually fuse elements all the way up to iron in the core.
Once the fusion ceases in the core, the core will contract due to the immense gravity and the outer part of the star "falls" onto the core and rebounds to create a massive explosion. Depending on the mass of the core, it will either become a neutron star or black hole.
