Na-O Anticorrelation And HB I. The Na-O anticorrelation in NGC 2808
Eugenio Carretta, Angela Bragaglia, Raffaele Gratton +3
We derived atmospheric parameters and elemental abundances of Fe, O and Na for about 120 red giant stars in the Galactic globular cluster NGC 2808. Our results are based on the ana…
Sulphur abundance in Galactic stars
E. Caffau, P. Bonifacio, R. Faraggiana +3
We investigate sulphur abundance in 74 Galactic stars by using high resolution spectra obtained at ESO VLT and NTT telescopes. For the first time the abundances are derived, where…
Li in NGC 6752 and the formation of globular clusters
L. Pasquini, P. Bonifacio, P. Molaro +5
Li abundances for 9 Turnoff (TO) stars of the intermediate metallicity cluster ([Fe/H]=-1.4) NGC6752 are presented. The cluster is known to show abundance anomalies and anticorrela…
The metal abundance distribution of the oldest stellar component in the Sculptor dwarf spheroidal galaxy
G. Clementini, V. Ripepi, A. Bragaglia +3
(abridged): Low resolution spectroscopy obtained with FORS2 at the Very Large Telescope (VLT) has been used to measure individual metal abundances ([Fe/H]) for 107 RR Lyrae stars,…
High-resolution spectroscopy of the old open cluster Collinder 261:abundances of Iron and other elements
Eugenio Carretta, Angela Bragaglia, Raffaele Gratton +1
We present the analysis of high resolution spectra of six red giant stars in the old open cluster Collinder 261. Reddening values for individual stars, derived from the relation be…
