  In these Canberra summer school lectures we treat a number of topical issues
in neutrino astrophysics: the solar neutrino problem, including the physics of
the standard solar model, helioseismology, and the possibility that the
solution involves new particle physics; atmospheric neutrinos; Dirac and
Majorana neutrino masses and their consequences for low-energy weak
interactions; red giant evolution as a test of new particle astrophysics; the
supernova mechanism; spin-flavor oscillations and oscillations into sterile
states, including the effects of density fluctuations; and neutrino-induced and
explosive nucleosynthesis.
