Popis: We have updated nuclear weak rates relevant to the study of astrophysical processes in stars. Neutrino-induced reaction cross sections, electron-capture and β-decay rates at stellar environments are obtained with new shell-model Hamiltonians that prove to be successful in describing spin responses — Gamow-Teller and spin-dipole transitions — in nuclei. The cross sections and rates are applied to nucleosynthesis in supernovae, detection of ν and nuclear URCA processes.
