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…
The Frequency of Carbon-Enhanced Metal-Poor Stars in the Galaxy from the HERES sample
Sara Lucatello, Timothy Beers, Norbert Christlieb +5
We estimate the frequency of Carbon-Enhanced Metal-Poor (CEMP) stars among very metal-poor stars, based on an analysis of 349 stars with available high-resolution spectra observed…
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…
