This Project Grant from the National Science Foundation's Mathematical and Physical Sciences program totaling $415,597 will fund research at Arizona State University on neutrino emission from stars from August 1, 2022 to July 31, 2025. The awardee will study neutrino production in stars across their life cycles using stellar evolution models spanning a wide range of initial masses. This will help analyze the impact of initial stellar composition, helium burning nuclear reaction rates, and neutral current de-excitation physics on the thermal and nuclear components of total neutrino luminosity. The results will provide targets for current neutrino telescopes to detect pre-supernova neutrinos and new predictions for individual stars and the collective stellar neutrino background signal. The research advances the goals of the NSF's Windows on the Universe Big Idea by probing astrophysics of neutrino production across the Hertzsprung-Russell diagram representing the full stellar population and lifecycle.
