Abstract

A simple model emphasizing an entropic view of VMO evolution in the oxygen core phase is developed. Calculations of the effects of the pair instability, oxygen and silicon burning, and alpha quenching on a global effective potential allow us to predict the critical oxygen core mass for black hole formation, MOc, and the abundance ratio of oxygen burning products to oxygen in those VMOs that explode. We find MOc ~ 102MƟ, corresponding to an initial star mass > 220 MƟ.
