Scientific paper

On the basis of a Monte Carlo code applied to the ejected envelope of SN 1987 A, as modeled by Nomoto et al. (1988), the future gamma-ray line emission of the object and the late behavior of the bolometric light curve are predicted. In addition to Co-57 and Ti-44, another radioactive isotope Co-60, produced by s-process in the helium burning shell of the supernova may have some influence on the UV-0-IR display at the end of 1990 and the beginning of 1991. The 122 keV line from Co-57 decay will be a prime target for the French-Soviet experiment Sigma and the American-French balloon Hirex (Jupiter III).
