The properties of the neutrino burst generated by massive 1.5-2 solar mass collapsing stellar iron-oxygen cores are discussed. Special attention is given to the neutrino heat conductivity theory which allows the transport of neutrinos to be calculated through the collapsing stellar core up to the formation and during the first seconds of cooling of a hot hydrostatic neutron star. The theoretical predictions seem to be in good agreement with both the Kamiokande II and IMB data on the neutrino burst detected from SN 1987A. The most reliable constraint on the neutrino rest mass is shown to be mnu of less than 20-30 eV.
