This star is the brightest example of a class of objects that, unlike the great majority of carbon-enhanced metal-poor (CEMP) stars, does not exhibit over-abundances of heavy neutron-capture elements (CEMP-no). In this paper, we validate the abundance determinations for a number of species that wer","authors_text":"Anna Frebel, Christopher Sneden, Dan Filler, Hendrik Schatz, Ian Roederer, Inese I.
