Nucleosynthesis with multi-dimensional supernova simulations

ORAL · Invited

Abstract

Core-collapse supernovae, the extremely energetic explosions of stars 10 times more massive than our sun, are known to be major contributors to the synthesis of the elements in the universe. Most of our understanding of these contributions is based on parameterized, spherically symmetric models. Only recently, multi-dimensional, self-consistent simulations have been carried out. Evaluating the nucleosynthesis of such large-scale simulations poses unique challenges and opens up new questions, that will be presented here. The first studies in this area, however, also show that there is a large potential for such simulations to address some long-standing tensions between theory and observations and due to the large variability of conditions predicted by the recent simulations, accurate predictions of the compositions requires knowledge of the nuclear properties and cross-sections on both sides of beta-stability.
