Scientific paper

Numerical simulations of exploding Population III stars, ending their lives as supernovae, are presented. Opal opacities are used for a series of calculations of solar, low, and z=0 metalicities and resultant luminosities versus time are compared. Single star evolution progenitor models are compared to stars evolved in binary systems with mass transfer. The resulting light curves and their corresponding redshifts produce possible signatures that may distinguish them from solar metalicity low redshift supernovae. Thus using only photometry it may be possible categorize these first stars. In addition supernovae progenitors originating in binary systems lead to radii that are almost three times larger than single stars. This will have a significant affect on the detection possibilities with JDEM and JWST. Photometric limits are also presented.
