The Origin of the Heavy Elements: Recent Progress in the Understanding of the r-Process
There has been significant progress in the understanding of the r-process
over the last ten years. The conditions required for this process have been
examined in terms of the parameters for adiabatic expansion from high
temperature and density. There have been many developments regarding
core-collapse supernova and neutron star merger models of the r-process.
Meteoritic data and observations of metal-poor stars have demonstrated the
diversity of r-process sources. Stellar observations have also found some
regularity in r-process abundance patterns and large dispersions in r-process
abundances at low metallicities. This review summarizes the recent results from
parametric studies, astrophysical models, and observational studies of the
r-process. The interplay between nuclear physics and astrophysics is
emphasized. Some suggestions for future theoretical, experimental, and
observational studies of the r-process are given.Comment: typos in Eqs. (30) and (31) correcte
