Scientific paper

Spectra of Supernova 1987A hard X-ray radiation forming due to Co-57 decay in the envelope and emission of the star remnant (a neutron star or an accreting black hole) in the envelope center are calculateed. This radiation can be detected in the near future due to the rapid decrease in the X-ray flux appearing due to Comptonization of the Co-56 gamma-ray photons in the envelope. The deviation of SN 1987A's bolometric optical and IR light curves from an exponential law with a fall time of about 114 days is studied.
