Scientific paper

It is shown that the properties of SN 1987A in the LMC can be described well by hydrodynamical models of explosions of compact massive stars. In accordance with these models, the mass of the expelled envelope, M, the presupernova radius, R, and the total energy of explosion, E, are evaluated for SN 1987A to be ≡16 M_sun;, ≡30 R_sun;, and ≡3×1051erg respectively. The progenitor of supernova remnant Cas A may be considered as the prototype of the SN 1987A in our own Galaxy. In other galaxies, this subtype of supernovae can be represented by SN 1948B in NGC 6946. If the energy of explosion transfers from the collapsed core of the star to its envelope with a characteristic time less than 1 hour, then delay of Δt ≡ 3 hours between the neutrino pulse and the steep rise of optical luminosity of SN 1987A does not contradict to the scenario of explosions of compact massive stars.
