<br>

"Explosive nucleosynthesis of heavy elements" <br>
<br>
Tuesday, 25th of November, 14:15h, F-102 <br>
<br>
Abstract: <br>
In this talk, I will review our current understanding of the<br>
nucleosynthesis of heavy elements in explosive environments by
the<br>
so-called r-process. The two major astrophysical sites currently<br>
considered are core-collapse supernova and neutron star mergers.
Each<br>
of them demands different nuclear physics ingredients for the<br>
nucleosynthesis modeling. In core-collapse supernova, the<br>
nucleosynthesis depends mainly on the neutron-richness of the
ejecta<br>
that is determined by the spectral differences between the
emitted<br>
electron neutrinos and antineutrinos. This difference is
particularly<br>
sensitive to the nuclear symmetry energy at subsaturation<br>
densities. Neutron star mergers are expected to eject material
that is<br>
so neutron rich that the nucleosynthesis becomes very robust and<br>
almost independent of the astrophysical conditions. However, it
is<br>
very sensitive of the nuclear properties of the very exotic
neutron<br>
rich nuclei that are produced during the nucleosynthesis<br>
event. Particularly important nuclear properties are masses,<br>
beta-decay rates and fission properties of neutron rich
superheavy<br>
nuclei.<br>
<br>
Best regards, <br>
