SYMM 1.3: Invited Talk

Tuesday, March 11, 2025, 12:00–12:30, Kurt-Alder HS Chemie

The r-process: connecting astrophysics and nuclear physics — •Almudena Arcones — Institut für Kernphysik, Technische Universität Darmstadt, Germany — GSI Helmholtzzentrum für Schwerionenforschung GmbH, Darmstadt, Germany — Max-Planck-Institut für Kernphysik, Heidelberg, Germany

Our understanding of the origin of heavy elements by the r-process (rapid neutron capture process) has made great progress in the last years. In addition to the gravitational wave and kilonova observations for GW170817, there have been major advances in the hydrodynamical simulations of neutron star mergers and core-collapse supernovae, in the microphysics included in those simulations (neutrinos and high density equation of state), in galactic chemical evolution models, in observations of old stars in our galaxy and in dwarf galaxies, and in nuclear theory and experiments. This talk will report on recent breakthroughs in understanding the extreme environments in which the formation of the heavy elements occurs, as well as open questions regarding the astrophysics and nuclear physics involved.
