Abstract: (ADS)
Detailed calculations are made of the neutrino spectra emitted during gravitational collapse events (Type II supernovae?). Those aspects of the neutrino signal which are relatively independent of the collapse model and those aspects which are sensitive to model details are discussed. The easier to detect high-energy tail of the emitted neutrinos has been calculated using the Boltzmann equation. This is compared with the result of the traditional multigroup flux-limited diffusion calculations. The harder to detect electron antineutrino background from historical supernovae might be enhanced by matter oscillation of higher energy mu and tau neutrinos to electon antineutrinos.References(22)
