Detection of Lead in the Carbon-rich, Very Metal-poor Star LP 625-44: A Strong Constraint on s-Process Nucleosynthesis at Low Metallicity

Aoki, Wako; Norris, John; Ryan, Sean G; Beers, Timothy C; Anderson, W G


We report the detection of the Pb I λ4057.8 line in the very metal-poor ([Fe/H] = -2.7), carbon-rich star, LP 625-44. We determine the abundance of Pb ([Pb/Fe] = 2.65) and 15 other neutron-capture elements. The abundance pattern between Ba and Pb agrees
