Low-energy neutrinos in astrophysics

Neutrinos play an important role in astrophysics. In connection with their extremely weak interaction with matter, they are able to escape from the interior of stars and to reach earth through large amounts of otherwise nontransparent matter. The current status of low energy neutrino astrophysics is considered, taking into account the latest results of the Brookhaven Solar Neutrino Experiment, standard solar model calculations, and a comparison of measured and theoretical values. Attention is also given to recent progress concerning the preparation of new solar neutrino detectors, and the prospects for the observation of neutrino radiation from collapsing stars
