Abstract

We study the fate of core-collapse supernovae from the massive stars by numerical simulations of neutrino-radiation hydrodynamics. We follow the long term evolution over 1 sec after the core bounce from the initial gravitational collapse to examine the explosion mechanism and to reveal the formation of neutron star and black hole. We explore the effects of equation of state (EOS) in these simulations by adopting the two sets of realistic EOS for supernovae. For the case of a 40M star, we find that the formation of black hole occurs in different timing depending on the softness of EOS and resulting properties of emergent neutrinos appear differently from ordinary supernova neutrinos.
