Neutrino Processes in the Sun and Supernovae
A.B. Balantekin
Dept. of Physics, University of Wisconsin-Madison


During the last thirty years experiments measuring the flux of electron neutrinos coming from the sun revealed a rate smaller than that predicted by the standard model of the sun. In this colloquium first a status report on the solar neutrino experiments will be given, emphasizing the role of future experiments. The relationship between the outcome from solar, atmospheric, and supernovae neutrino experiments will be highlighted.

The significance of neutrino masses, mixings between different families, and neutrino interactions with matter in the sun and supernovae along with the implications for cosmology will be discussed. In particular the role of neutrinos in supernova shock reheating and r-process nucleosynthesis in a supernovae will be highlighted. Implications of density fluctuations in the sun and supernova hot bubble for neutrino processes will be presented.
