Diagnostics for Thermonuclear and Core-Collapse Supernovae

I will likely present some new results on (a) variations of silicon group yields with initial metallicity ($^{22}$Ne) in Type Ia supernovae models, and (b) trends in the yield of $^{44}$Ti and $^{56}$Ni as a function of the initial shock density, temperature, and electron fraction in core-collapse supernovae models.
