description

Abstract We compare calculations of r-process abundances with recent astronomical observations from extremely metal-deficient, neutron-capture-rich halo stars. We derive criteria to determine Th and U chronometric ages, and deduce astrophysical conditions under which the observed abundance patterns can be obtained under r-like conditions.
