Abstract

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.
