Abstract
We have computed the ejection of a massive envelope by a star during a type II supernova explosion in the presence of a compact remnant (a neutron star or black hole). This problem is of interest because of the possible presence of a compact remnant following the SN 1987A explosion. The computations demonstrate that a fairly large amount of matter is left in the neighborhood of the compact gravitating body. We present computations of the accretion rate onto the surface of the compact remnant. The estimated luminosity exceeds that observed for SN 1987A in various frequency ranges by several orders of magnitude.
