Supernova neutrinos

In this paper, we summarize some of the new ideas concerning supernova neut rinos and their angular, spatial, and energy distributions in protoneutron stars. Furthermore, we touch on some of the recent speculations concerning the systematics with progenitor mass of core-collapse supernova explosion e nergies and Ni-56 yields. In addition, we discuss some of the prominent fea tures predicted in galactic neutrino bursts, features that would be detecte d by underground neutrino telescopes now on line. Recently, a few theoretic al teams have started to explore afresh neutrino-matter interactions and hi gh-precision algorithms for determining the neutrino radiation fields. We p resent some preliminary results from one of those teams.
