Abstract

Accurate estimates of (anti)neutrino spectra and luminosities are needed to determine the possibility of pre-supernova neutrino detection. Using the recently proposed thermal quasiparticle random-phase approximation (TQRPA) method, we have studied thermal effects on the spectra and luminosities of (anti)neutrinos emitted in nuclear weak-interaction processes under pre-supernova conditions. We show that a thermodynamically consistent consideration of Gamow–Teller transitions in hot nuclei increases the energy luminosity and results in larger average (anti)neutrino energies.
