STARS AS GALACTIC NEUTRINO SOURCES

Theoretical expectations concerning stars as neu- trino sources are presented according to detailed evaluations of the stellar evolutionary histories for an extended grid of stel- lar masses. Neutrino fluxes and cumulative neutrino yields are given for both 'thermo-nuclear' and 'cooling' neutrinos all over the nuclear life of the stars and along the final cooling as White Dwarfs. Predictions concerning the galactic and the cosmic neu- trino background are presented and discussed.
