A very low mass of 56 Ni in the ejecta of SN 1994

Abstract

We present spectroscopic and photometric observations of the luminous narrow-line Type IIP (plateau) supernova 1994W. After the plateau phase (t ∼> 120 days), the light curve dropped by ∼ 3.5 mag in V in only 12 days. Between 125 and 197 days after explosion the supernova faded substantially faster than the decay rate of Co, and by day 197 it was 3.6… (More)
