Supernova Nucleosynthesis with modern Supernova Simulations*

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.
