An insipid CH star in the Sculptor dwarf spheroidal galaxy.
SHETRONE M.D., BRILEY M. and BREWER J.P.
Abstract (from CDS):
A strong CN star in the Sculptor dwarf spheroidal galaxy discovered by Smith & Dopita (1983ApJ...271..113S) has been found to be an insipid CH star. This star, Sculptor 314, exhibits both strong CN bands and strong CH bands ruling out any similarity with CN strong stars found in most globular clusters. No C2 bands are found in its spectra. Based on the derived abundances, when Sculptor 314 evolves further up the giant branch it will not develop strong C2 and will not appear similar to those CH stars which have been found by previous searches.
