Stars as galactic neutrino sources

TL;DR

This paper evaluates stars as sources of neutrinos by modeling their evolutionary histories, providing flux predictions for different neutrino types throughout stellar lifecycles, and discussing implications for galactic and cosmic neutrino backgrounds.

Contribution

It offers detailed theoretical predictions of neutrino fluxes from stars across various evolutionary stages, including White Dwarfs, which is a novel comprehensive analysis.

Findings

Neutrino fluxes vary significantly during stellar evolution.

Predicted neutrino backgrounds contribute to galactic and cosmic neutrino signals.

White Dwarfs are notable neutrino sources in the late stellar stages.

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.
