Neutrinos from Collapsing Stars and SN1987A

Abstract

Weak interaction processes leading to the production and emission of neutrinos from collapsing stars are reviewed. Based on recent numerical simulations it is shown that: 1. Only electron neutrinos are emitted during the core collapse phase and the short deleptonization burst with a typical luminosity of about 1053erg s−1 and 1054erg s−1. respectively; 2. during a first cooling phase lasting for a few seconds neutrinos and anti-neutrinos of all flavours are emitted with typical energies between 10 and 20 MeV and a total luminosity per species of about a few times 1052erg s−1. These theoretical predictions are compared with the neutrino energies and luminosities inferred from supernova 1987A.
