Description
Numerous signatures of r- and s-process nucleosynthesis can be observed in the
photospheres of stars. To date, however, the stellar abundance determinations of
many of the elements have been scarce because a large portion of the dominant
atomic transitions reside in the UV. To be reported in the context of other recent
results of neutron-capture studies, are the abundances (or upper limits) of Nb, Pd,
Ag, Yb, Hf, Pt, Pb, and other neutron-capture elements for a sample of stars
observed with the near-UV sensitive detector on the High Resolution Echelle
Spectrometer of the Keck I telescope.
