The authors predict the emergence of X-rays from SN 1987A. The predictions are based on detailed models for the elemental and density stratification of the supernova provided by Woosley, Pinto, and Ensman and the assumption that the optical light curve is due either to radioactive decay of 56Co or to a luminous X-ray source at the center with a spectrum like that of the Crab Nebula. They show how the emergence of the X-ray spectrum depends on the parameters of the model and the nature of its central energy source. They also show that the soft X-ray spectrum should be dominated by a 6.4 keV Fe Kα emission line that could be observed by a sensitive X-ray telescope.
