Supernova 1987K - Type II in youth, type Ib in old age

Abstract

Spectra of SN 1987K in NGC 4651 have been obtained 0-2 weeks past maximum brightness and 5-7 weeks past maximum. The results suggest that SNe II and at least some SNe Ib are closely related objects, and that SN 1987A could have been a massive star which lost a majority of its hydrogen prior to exploding. It is proposed that SN 1987A belongs to a new subclass, type IIb, of SN that have the spectral characteristics of type II near maximum brightness and those of type Ib long past maximum. 64 references.
