Light curve of type I supernovae

PDF Version Also Available for Download.

Description

Calculations of the intermediate and late time luminosity of type I supernovae based on 100% efficiency for optical emission of energy deposited by the Ni/sup 56/ decay chain give good agreement with observations provided M/sub ej/ v/sup -2/ = (2.2 +- 0.5) x 10/sup 17/ M. s/sup 2/ cm/sup -2/ where M/sub ej/ is the ejected mass an v is the expansion velocity. Account must be taken of the escape of both gamma rays and positrons. These two escape processes as well as the early luminosity peak as calculated by Colgate and McKee are all consistent with the same value ... continued below
