WebObservations combined with theoretical modeling of the light curve of 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 … SN 1997D è una supernova del tipo II che è stata scoperta per l'astronoma ed astrofisica brasiliana Duília de Mello in 14 gennaio 1997, durante un'osservazione in Cile nell'osservatorio ESO con il telescopio di 1,52m in La Silla. La SN 1997D è localizzata a 11' est e 43" sud del nucleo della galassia NGC 1536.
