Ti44 and Ni56 in core-collapse supernovae

Abstract

We investigate the physical conditions where 44 Ti and 56 Ni are created in core-collapse supernovae. In this preliminary work we use a series of post-processing network calculations with parameterized expansion profiles that are representative of the wide range of temperatures, densities and electron-to-baryon ratios found in 3D supernova simulations. Critical flows that affect the final yields of 44 Ti and 56 Ni are assessed.
