Abstract
The recognition that the metallicity of Type Ia supernova (SNIa) progenitors might bias their use for cosmological applications has led to an increasing interest in its role in shaping SNIa light curves. We explore the sensitivity of the synthesized mass of 56Ni, M(56Ni), to the progenitor metallicity starting from pre-main-sequence models with masses M0 = 2–7 M_ and metallicities Z = 10-5–0.10. The interplay between convective mixing and carbon burning during the simmering phase eventually ...
