Abundances of Rarely Detected s-process Elements Derived from the Ultraviolet Spectrum of the s-process-enhanced Metal-poor Star HD 196944

We present an analysis of the heavy-element abundances of HD 196944, a carbon-enhanced metal-poor (CEMP) star enriched with elements produced by the slow neutron-capture process ( s -process). We obtained a new high-resolution ultraviolet (UV) spectrum of this star, the UV-brightest known CEMP- s st...
