RECENT PROGRESS AND PROSPECTS IN
SOLAR, ATMOSPHERIC, AND SUPERNOVA NEUTRINO PHYSICS
A.B. Balantekin

Recent experimental and theoretical developments in solar and
atmospheric neutrino physics are reviewed. The complementary aspects
of the data from the solar neutrino experiments and helioseismological
observations are discussed. The possibility of doing innovative solar
(as opposed to neutrino) physics with the solar neutrino data are
explored. Core-collapse supernovae are excellent laboratories to study
the consequences of neutrino mass and mixings. In this talk
active-sterile neutrino conversion in the late time post-core-bounce
supernova environment is examined. By including the effect of feedback
on the Mikheyev-Smirnov-Wolfenstein conversion potential, a large range
of neutrino mixing parameters which produce a favorable environment for
the r-process nucleosynthesis are obtained. The importance of the
complementary laboratory experiments in nuclear astrophysics will be
emphasized.
