Scientific paper

Results from a study of the effects of convection on the early life of a neutron star and the mechanism of type II supernovae are presented. It is found that entropy-driven convection can enhance the neutrino luminosities in the quasi-static postcollapse stage of the core of a massive star by at times an order of magnitude. Furthermore, the neutrinospheric temperatures and, hence, the energy of the emitted neutrinos are increased by up to about 50 percent. These effects significantly strengthen the energy coupling between the core and the envelope. If these results are confirmed, convection must play a significant, perhaps pivotal, role in the long-term mechanism for type II supernovae.
