Testing the effect of progenitor's metallicity on ${}^{56}$Ni mass and constraining the progenitor scenarios in Type Ia supernovae

Young-Lo Kim, Chul Chung, Yong -Cheol Kim

The analytical model found that the intrinsic variation in the initial metallicity of the Type Ia supernova (SN Ia) progenitor stars ($Z_{progenitor}$) translates into a 25% variat…
