Solar, Supernova, and Atmospheric Neutrinos

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.
