Heavy elements like Gold and Uranium are produced by the rapid neutron capture
process (r-process). Extreme neutron-rich conditions are necessary for this
process, which is linked to neutron stars. Two possible astrophysical
scenarios have been suggested as the site of the r-process: core-collapse
supernovae (where neutron stars are born) and neutron star mergers. In 2017,
gravitational waves were detected from the merger of two neutron stars,
GW170817, opening a new multimessenger era. Observations of this event
revealed that heavy, neutron-rich nuclei were produced. These nuclei are
unstable and their decay leads to a kilonova light curve. In the talk, I will
present the nucleosynthesis in neutron star mergers and discuss the critical
contribution of core-collapse supernovae to the chemical history of the
universe.
