2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/83141In 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.To be published in the Proceedings of the 1998 Australian National University Nuclear Physics Summer School; S.
