Discovery of Carbon/Oxygen depleted Blue Straggler Stars in 47 Tucanae: the chemical signature of a mass-transfer formation process
F. R. Ferraro, E. Sabbi, R. Gratton +10
We use high-resolution spectra obtained with the ESO Very Large Telescope to measure surface abundance patterns of 43 Blue Stragglers stars (BSS) in 47 Tuc. We discovered that a su…
On the Iron content of NGC 1978 in the LMC: a metal rich, chemically homogeneous cluster
Francesco R. Ferraro, Alessio Mucciarelli, Eugenio Carretta +1
We present a detailed abundance analysis of giant stars in NGC 1978, a massive, intermediate-age stellar cluster in the Large Magellanic Cloud, characterized by a high ellipticity…
Na-O Anticorrelation And HB. III. The abundances of NGC 6441 from FLAMES-UVES spectra
R. G. Gratton, S. Lucatello, A. Bragaglia +4
The aim of the present work is to determine accurate metallicities for a group of red giant branch stars in the field of the bulge Globular Cluster NGC 6441. This is the third pape…
The metallicity of the old open cluster NGC 6791
Raffaele Gratton, Angela Bragaglia, Eugenio Carretta +1
We have observed four red clump stars in the very old and metal-rich open cluster NGC 6791 to derive its metallicity, using the high resolution spectrograph SARG mounted on the TNG…
