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).
