BOLOMETRIC LIGHT CURVES FOR 33 TYPE II PLATEAU SUPERNOVAE

Bersten, MC; Hamuy, M.

Abstract

Using data of three well observed Type II plateau supernovae (SNe II-P), SNe 1987A, 1999em, and 2003hn, and two atmosphere models by Eastman et al. and Dessart & Hillier, we derive calibrations for bolometric corrections and effective temperature from BVI photometry. The typical scatter of the bolometric correction is 0.11 mag. With these results we obtain bolometric light curves and effective temperature evolution for a sample of 33 SNe II-P. The SN sample shows a range of 1 dex in plateau luminosity and plateau durations from 75 to 120 days. Comparing the shape of the transition between the plateau and the radioactive tail, we find that the size of the drop is in the range of 0.8-1.12 dex. © 2009. The American Astronomical Society.
