Abstract

Observations combined with theoretical modeling of the light curve cf the recently discovered supernova 1997D in NGC 1536 suggest that it might host a black hole formed in the aftermath of the explosion. We consider some observable consequences of a black hole in SN 1997D and estimate the late-time accretion luminosity of the material that falls back onto the hole. We find that this luminosity, decaying with a characteristic power-law dependence on time, may emerge above the emission of the envelope in just a few years. Its detection would thus provide unmistakable evidence for the presence of a black hole.
