Abstract

Theoretical expectations concerning stars as neutrino sources are presented according to detailed evaluations of the stellar evolutionary histories for an extended grid of stellar 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 neutrino background are presented and discussed.

Key words: Sun: particle emission – stars: evolution – stars: general
