Scientific paper

Prompted by the recent hard X-ray and γ-ray observations of SN 1987A by the satellites (Ginga, Kvant, and SMM) and the balloons, theoretical light curves and spectra of X rays and γ-rays are calculated and compared with the observations to make predictions for future observations. In the theoretical model, line γ-rays are emitted from decaying 56Co and degraded into hard X-rays due to Compton scatterings. The calculation can cosistently account for the early emergence and the subsequent light curves of γ-rays and hard X-rays and the spectral evolution if some mixing of 56Co and other heavy elements into outer hydrogen-rich layers is assumed.
