Abstract: Neutron star mergers are among the most extreme events in the Universe, providing a unique laboratory to study matter at densities and temperatures inaccessible on earth. While much of our understanding of these events relies on the properties of matter in equilibrium, the rapid dynamics of a merger can drive matter far from equilibrium.

Abstract: The GSI accelerator facility currently hosts two storage rings, the Experimental Storage Ring (ESR) and the low-energy storage ring CRYRING@ESR, which together cover a wide range ion species and beam energies and are used mainly for experiments on atomic and nuclear physics. This talk will focus mainly on dielectronic recombination experiments performed at CRYRING@ESR but will also present a proposed experiment on nuclear excitation by electron capture (NEEC).

Abstract: The actinides, including thorium (Th), are the heaviest observable elements synthesized in the universe, holding clues to the extremes of the astrophysical and nuclear conditions of r-process sites. I present Th abundances based on high-resolution spectroscopy for 47 metal-poor stars, the largest homogeneously analyzed sample to date.

Abstract: The reaction 22Ne(𝛼,𝑛)25Mg is one of the main neutron source in stars, providing the neutron flux for the weak component of the s-process in massive stars and partially contributing to the main component in AGB stars. For these reasons, its reaction rate is crucial in nuclear astrophysics.

However, the limited availability of experimental data in the energy range of astrophysical interest still leads to significant uncertainties in the reaction rate and in nucleosynthesis predictions.

Abstract: Nuclear clustering is a phenomenon where the structure of the nucleus tends towards clumps of alpha particles rather than a homogenous ball of protons and neutrons. Understanding this feature of the nuclear force is particularly important for astrophysics, for instance in the Hoyle state which is essential to the triple-alpha process.

Note that this seminar will take place at 9am Eastern Time / 3 pm CET and Daylight Savings Time has ended in the US.

Abstract: Stars are the element factories of the universe. Stellar explosions distribute freshly synthesized radionuclides in the interstellar medium and lead to the chemical enrichment of galaxies. These cataclysmic events moreover shape the interstellar medium and form large scale structures in the universe.
