Abstract
Neutrinos play an important role in the type-II supernova scenario. Numerous approaches have been made in order to treat the generation and transport of neutrinos and the interactions between neutrinos and matter during stellar collapse and the shock propagation phase. However, all computationally fast methods have in common the fact that they cannot avoid simplifications in describing the interactions and, furthermore, have to use parameterizations in handling the Boltzmann transport equation. In order to provide an instrument for calibrating these treatments and for calculating neutrino spectra emitted from given stellar configurations, a Monte Carlo transport code was designed. Special attention was payed to an accurate computation of scattering kernels and source functions. Neutrino spectra for a hydrostatic stage of a 20 M⊙. Supernova simulation were generated and conclusions drawn concerning a late time revival of the stalled shock by neutrino heating.
