Scientific paper

We examine the effects of multidimensional hydrodynamics on γ-ray emitting radionuclide yields from massive star progenitor supernovae. Significant differences are expected between explosive nucleosynthesis product yields from 1- and 2-dimensional hydrodynamical models due to the rather high perturbation amplitudes in density (10%), temperature (5%), and neutron excess (50%) realized in 2-dimensional simulations of pre-core collapse stellar evolution. Shocks are introduced into these models of pre-collapse evolution and are further evolved with a 160 isotope network coupled to our PPM hydro code.
