Using a new set of metallicity dependent SNIa yields, we identify isotopic abundances which differ between sub-Chandrasekhar and Chandrasekhar mass progenitors across an initial mass fraction of Ne-22 ranging from 0 to 0.1.
This presents a robust constraint on nucleosynthetic tracers of progenitor mass which are insensitive to initial metallicity.

Taking these tracer isotopes, we then investigate the contribution to the solar composition from sub- and Chandrasekhar mass explosions using the one zone GCE code OMEGA.
