21. r-process nucleosynthesis in compact object mergers

Oral Contribution

Thirty years after both the light and neutrino emission was observed from SN1987A, the neutron star merger event GW170817 demonstrated the power of new tools in multi-messenger astronomy. Since LIGO/VIRGO gravitational wave detection enables identification and pointed electromagnetic follow-up of merger events, new insights into these rare and interesting systems can be gained. The...

27. Nucleosynthesis in core-collapse supernovae

Oral Contribution

Core-collapse supernovae (CCSNe) are one of the most important sites of element synthesis in the universe and drive the chemical evolution of galaxies. A major goal of CCSN nucleosynthesis studies is to determine how nucleosynthesis outcomes depend on progenitor properties (e.g. mass and metallicity) and the explosion details. Traditional calculations do not account for neutrino-matter...

11. Influence of astrophysical and nuclear physics uncertainties on the nucleosynthesis in core-collapse supernova neutrino-driven winds

Maximilian Jacobi (TU-Darmstadt)

Oral Contribution

Neutrino-driven winds emerging after a successful core-collapse
supernovae can produce the lighter heavy elements between Fe and Ag depending on the
properties of the ejecta.
However, despite the fast progress in supernovae simulations in the last
decades, there are still large uncertainties in the astrophysical
conditions.
We rely on a steady-state neutrino-driven wind model to
...

22. Inhomogeneous Galactic Chemical Evolution of r-process Elements

Benjamin Wehmeyer (Konkoly Observatory & Univ. of Hertfordshire)

Oral Contribution

The origin of the heaviest elements is still a matter of debate. For the rapid neutron
capture process (“r-process”), multiple sites have been proposed, e.g., neutron star
mergers and (sub-classes) of supernovae. R-process elements have been measured in
metal-poor halo stars. Galactic archaeology studies show that the r-process abundances
among these stars vary by over two orders of magnitude....
