Scientific paper

The initial burst of neutrino luminosity from a supernova is expected to last approximately 1 ms, in which approximately 10 to the 51st ergs are emitted from the shocked material in the outer core. A detectable fraction of this energy is expected to be in the form of electron antineutrinos, the exact value depending sensitively on the temperature behind the shock. During the deleptonization of the unshocked inner core, lasting approximately 1s, the neutrino energy of about 10 to the 52nd ergs is expected to be approximately blackbody radiation, with equal luminosities in neutrinos and antineutrinos.
