The chemical signature of a relic star cluster in the sextans dwarf spheroidal galaxy - Implications for near-field cosmology

Karlsson, Torgny; Bland-Hawthorn, Joss; Freeman, Kenneth; Silk, Joe


We present tentative evidence for the existence of a dissolved star cluster at [Fe/H] = -2.7 in the Sextans dwarf spheroidal galaxy. We use the technique of chemical tagging to identify stars that are highly clustered in a multi-dimensional chemical abundance space (-space). In a sample of six stars, three, possibly four, stars are identified as potential cluster stars. The initial stellar mass of the parent cluster is estimated from two independent observations to be , assuming a Salpeter...[Show more]
