Abstract
We study the gravitational collapse of non-rotating massive stars (40-50M odot;) and the associated neutrino burst by general relativistic v-radiation hydrodynamics. We show that the neutrino burst from the accreting proto-neutron star till the black hole formation is short and energetic in a situation of failed explosion. This unique characteristics is a hallmark of black hole formation and distinguishable from the neutrino signal of ordinary supernovae. Adopting the sets of physical equation of state of dense matter, we demonstrate that the duration of neutrino emission depends crucially on the equation of state. Future detection of neutrinos from the failed supernovae can be used to probe the stiffness of dense matter with possible emergence of hyperons. Speaker.
