THE EFFECT OF PROGENITOR AGE AND METALLICITY ON LUMINOSITY AND Ni-56 YIELD IN TYPE Ia SUPERNOVAE
Timmes et al. found that metallicity variations could theoretically account for a 25% variation in the mass of 56Ni synthesized in Type Ia supernovae (SNe Ia), and thus account for a large fraction of the scatter in observed SN Ia luminosities. Higher-metallicity progenitors are more neutron rich, p...
