The Populations of Carina. II. Chemical Enrichment
Norris, John; Yong, David; Venn, Kim; Gilmore, Gerard; Casagrande, Luca; Dotter, Aaron
Chemical abundances are presented for 19 elements in a sample of 63 red giants in the Carina dwarf spheroidal galaxy (dSph), based on homogeneous 1D/LTE model atmosphere analyses of our own observations (32 stars) and data available in the literature (a further 31 independent stars). The (Fe) metallicity and [α/Fe] distribution functions have mean values and dispersions of −1.59 and 0.33 dex ([Fe/H] range: −2.68 to −0.64) and 0.07 and 0.13 dex ([α/Fe] range: −0.27 to 0.25), respectively.
