Supernova Nucleosynthesis with modern Supernova Simulations
ORAL
Abstract
Supernova explosions of massive stars pose a very complicated mulit-physics
problem but they are key to understand the chemical composition of the solar
system. Self-consistent, numerical simulations of
supernova explosions have made great progress in the last decade and
I am going to show results from nucleosynthesis calculations based
on a self-consistent, three-dimensional supernova simulation and highlight the
challenges that need to be adressed in order to obtain accurate nucleosynthesis
predictions from state-of-the art supernova simulations. Implications of those results
for the presence of long-lived radioactive isotopes in the early solar system
are discussed, including the 10Be, which is produced by neutrino-nucleus interactions.
