Description

We will discuss new results on nucleosynthesis in core-collapse supernovae and neutrino-driven winds that produce elements up to silver. Because the synthesis of these elements occurs closer to stability, in the near future, the nuclear physics uncertainties will be reduced by experiments. This will uniquely allow us to combine observations and nucleosynthesis calculations to constrain the astrophysical conditions in neutrino-driven winds and thus gain new insights about core-collapse supernovae. In addition, we will discuss the production of all r-process elements (from the first to the third peak) in neutron star mergers. The radioactive decay of neutron-rich nuclei triggers a electromagnetic signal in mergers known as kilonova. This was potentially observed after a short gamma ray burst, associated with a neutron star merger. Nucleosynthesis in mergers takes place far away from stability and our sensitivity studies show the importance of, in particular, nuclear masses and fission properties.
