Notes. Mc is the mass of the oxygen core, Ebind the initial binding energy, ρc the initial central density, Tmax the maximum temperature at the center at the moment of reversal of collapse, Enuc the total nuclear energy release. PISN – the model explodes without any remnant, CC – collapse at the center of the core.
