Astrophysical Models of r-Process Nucleosynthesis: An Update [PDF]
Yong-Zhong QianAn 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.View original: http://arxiv.org/abs/1201.5112
