Abundances of trace elements in HR 465: evidence for the r-process

Description

Abundances have been derived for eight elements in HR 465 near the r-process peaks at tellurium and osmium. Elements on the peaks are decidedly enhanced relative to those in the nearby "troughs." If we add to this information the presence of uranium, a strong case can be made that the abundances n HR 463 reflect a substantial amount of r-processing.
