Terzan 8: a Sagittarius-flavoured globular cluster
Eugenio Carretta, Angela Bragaglia, Raffaele G. Gratton +3
Massive globular clusters (GCs) contain at least two generations of stars with slightly different ages and clearly distinct light elements abundances. The Na-O anticorrelation is t…
Carbon-enhanced Metal-poor Stars in SDSS/SEGUE. I. Carbon Abundance Estimation and Frequency of CEMP Stars
Young Sun Lee, Timothy C. Beers, Thomas Masseron +8
We describe a method for the determination of stellar [C/Fe] abundance ratios using low-resolution (R = 2000) stellar spectra from the SDSS and SEGUE. By means of a star-by-star co…
Rubidium abundances in the globular clusters NGC 6752, NGC 1904 and NGC 104 (47 Tuc)
Valentina D'Orazi, Maria Lugaro, Simon W. Campbell +5
Large star-to-star variations of the abundances of proton-capture elements, such as Na and O, in globular clusters (GCs) are interpreted as the effect of internal pollution resulti…
NGC 362: another globular cluster with a split red giant branch
E. Carretta, A. Bragaglia, R. G. Gratton +7
We obtained FLAMES GIRAFFE+UVES spectra for both first and second-generation red giant branch (RGB) stars in the globular cluster (GC) NGC 362 and used them to derive abundances of…
The Tenth Data Release of the Sloan Digital Sky Survey: First Spectroscopic Data from the SDSS-III Apache Point Observatory Galactic Evolution Experiment
Christopher P. Ahn, Rachael Alexandroff, Carlos Allende Prieto +232
The Sloan Digital Sky Survey (SDSS) has been in operation since 2000 April. This paper presents the tenth public data release (DR10) from its current incarnation, SDSS-III. This da…
Infrared photometry of Young Massive Clusters in the starburst galaxy NGC 4214
A. Sollima, R. G. Gratton, E. Carretta +2
We present the results of an infrared photometric survey performed with NICS@TNG in the nearby starburst galaxy NGC 4214. We derived accurate integrated JK magnitudes of 10 young m…
