Scientific paper

In this paper, the neutrino mass has been determined from SN 1987a observation in a manner that the simultaneity of neutrino emission is not regarded as the starting point, but is itself defined through the analysis by Monte-Carlo simulation. The result is that the neutrino mass lies in the 3-4 eV range, possibly mv of about 3.6 eV. Neutrino luminosity variations and neutrino spectrum are also obtained. Comparison with theories gives further support to the mass determination, and also predicts the mass of the progenitor star of SN 1987a to be in the range of 12-25 solar masses.
