Title: The Long Term Supernova Neutrino Signal

Abstract: After a successful, neutrino driven core collapse supernova, a protoneutron star is left behind as a remnant. This hot, extended young neutron star cools and contracts over a period of tens of seconds emitting a copious number of neutrinos. The spectrum and time dependence of this neutrino emission encodes information about the properties of dense matter, sets the initial conditions for neutrino oscillations, and can impact nucleosynthesis in the supernova. I will present models of protoneutron star cooling that follow and discuss prospects for detection of these neutrinos from a nearby supernova. Then, I will talk about how microphysics, including neutrino opacities and the nuclear equation of state, impacts protoneutron star cooling and nucleosynthesis in these environments.
