Late Light Curves of the Subluminous SN 2005mz
Abstract
Light curves of Type Ia supernovae (SNe Ia) are powered by the decay of "56Ni→56Co→56Fe" . The late light curves (after approximately 200 days past the peak) are powered by the deposition of positron kinetic energy from the decay of 56Co into the supernova ejecta. A study of the late light curves of normally-luminous SNe Ia showed that the slopes of the light curves are more shallow than expected from energy deposition models (Lair et al. 2006). The subluminous SNe Ia are the least studied sub-class of SNe Ia, particularly at late times. We present the BVRI late time light curve of the subluminous SN 2005mz.
