Nucleosynthesis of heavy nuclei -- moving a supernova into the laboratory — •Felix Heim — University of Cologne, Institute for Nuclear Physics

Stars do not only produce visible light and energy via nuclear fusion reactions but are also responsible for the creation of heavy elements. Since its birth over 60 years ago, the field of nuclear astrophysics strives to describe the complex nuclear processes and astrophysical conditions that drive elemental nucleosynthesis. While many facets of this topic are well-understood, others do still remain a great puzzle. Many heavy isotopes are produced within explosive stellar scenarios such as supernova explosions or neutron-star merger events. The procedure and the outcome of these events is heavily affected by nuclear reactions and the rates at which they occur. Therefore, it is essential to study the relevant nuclear reactions in the laboratory and mimic the stellar conditions. Furthermore, theoretical models have to be employed in many cases, where no experimental data are yet available. Therefore systematic investigation and testing of the underlying nuclear physics parameters is essential.

This contribution will discuss some experimental techniques to study nuclear reactions under astrophysical conditions using ion beam accelerators. In addition, current experimental results will be put into context of modern theoretical models using statistical methods. Supported by the DFG (ZI 510/8-2).
