Abstract:
Homogeneous abundances of light elements, alpha-elements, Fe-group
elements and neutron-capture elements from high-resolution FLAMES
spectra are presented for stars in the globular cluster NGC 5634,
associated to the Sagittarius dwarf spheroidal galaxy. In particular
we present detailed chemical abundance of 22 species for the seven
stars observed with UVES-FLAMES, and the abundance of six elements for
stars observed with GIRAFFE. We derived a metallicity
[Fe/H]=-1.867±0.019±0.065dex (±statistical±systematic error)
with sigma=0.050dex (7 stars). We found the normal anti-correlations
between light elements (Na and O, Mg and Al), signature of multiple
populations typical of massive and old GCs. We confirm the
associations of NGC 5634 to the Sgr dSph, from which the cluster was
lost a few Gyr ago, on the basis of its velocity and position, and the
abundance ratios of α and neutron capture elements.
Description:
For a sample of 43 stars in NGC 5634 observed with FLAMES@VLT we give
here: identifications, coordinates, VIK magnitudes, heliocentric RV
(table2).
