We examine the Pb and Th abundances in 27 metal-poor stars (−3.1 56) enrichment was produced only by the rapid (r-) nucleosynthesis process. New abundances are derived from HubbleSpace Telescope/Space Telescope Imaging Spectrograph, Keck/High Resolution Echelle Spectrograph, and Very Large Telescope/UV–Visual Echelle Spectrograph spectra and combined with other measurements from the literature to form a more complete picture of nucleosynthesis of the heaviest elements produced in the r-process… CONTINUE READING
