J/A+A/578/A116 Abundances of red giant stars in NGC6093 (M80) (Carretta+, 2015) ================================================================================ Detailed abundances of a large sample of giant stars in NGC 6093 (M80).

Bragaglia A., Gratton R., D'Orazi V., Lucatello S., Sollima A., Momany Y., Catanzaro G., Leone F. =2015A&A...578A.116C ================================================================================ ADC_Keywords: Clusters, globular ; Stars, giant ; Abundances Keywords: stars: abundances - stars: Population II - globular clusters: general - globular clusters: individual: NGC 6093 (M 80) - stars: atmospheres Abstract: Homogeneous abundances of light elements, alpha-elements, and Fe-group elements from high-resolution FLAMES spectra are presented for 82 red giant stars in NGC 6093 (M 80), a dense, metal-poor globular cluster (GC). M 80 shows star to star variations in proton-capture elements, and the extension of the Na-O anticorrelation perfectly fit the relations with (i) total cluster mass, (ii) horizontal branch morphology, and (iii) cluster concentration previously found by our group. The chemistry of multiple stellar populations in M 80 does not look extreme. The cluster is also a typical representative of halo globular clusters for what concerns the pattern of alpha-capture and Fe-group elements. However we found that a significant contribution from the s-process is required to account for the distribution of neutron-capture elements. Description: For a sample of 143 stars in M80 observed with FLAMES@VLT we give here: identifications, coordinates, BV magnitudes, heliocentric RV (table2). For members we also give: atmospheric parameters, [Fe/H] (table 3); [O/Fe], [Na/Fe], [Mg/Fe], [Al/Fe] (table 5); the alpha-elements Si, Ca, and Ti (table 6); the Fe-peak elements Sc, V, Cr, Mn, Co, Ni, Cu, and Zn (table 7); the n-capture elements Y, Zr, La, Ce, Pr, Nd, Sm, (table 8, only UVES stars); Ba (table 9).
