Scientific paper

An update on astrophysical models for nucleosynthesis via rapid neutron
capture, the r process, is given. A neutrino-induced r process in supernova
helium shells may have operated up to metallicities of ~10^-3 times the solar
value. Another r-process source, possibly neutron star mergers, is required for
higher metallicities.
