THE RISE TIME OF NORMAL AND SUBLUMINOUS TYPE Ia SUPERNOVAE

Abstract:

We calculate the average stretch-corrected rise time of Type Ia supernovae (SNeIa) in the Supernova Legacy Survey. We use the aggregate light curves of spectroscopic and photometrically identified SNeIa to fit the rising part of the light curve with a simple quadratic model. We obtain a light curve shape corrected, i.e., stretch-corrected, fiducial rise time of 17.02 +0.18-0.28 (stat) days. The measured rise time differs from an earlier finding by the SNLS (Conley etal.) due to the use of dif...
