The Peculiar Type Ic Supernova 1997ef: Another Hypernova
Koichi Iwamoto,T. Nakamura,Ken'ichi Nomoto,Paolo A. Mazzali,I. J. Danziger,P. M. Garnavich,Robert P. Kirshner,Saurabh Jha,David D. Balam,John R. Thorstensen +9 more
TL;DR: In this paper, the authors show that the spectral properties of the Type Ic supernova SN 1997ef suggest that it may also be a hypernova, based on the broad absorption lines of oxygen and iron.
