On a new Near-Infrared method to estimate the absolute ages of star clusters: NGC3201 as a first test case
G. Bono, P. B. Stetson, D. A. VandenBerg +24
We present a new method to estimate the absolute ages of stellar systems. This method is based on the difference in magnitude between the main sequence turn-off (MSTO) and a well d…
Chemical abundances for 11 bulge stars from high-resolution, near-IR spectra
N. Ryde, B. Gustafsson, B. Edvardsson +10
It is debated whether the Milky Way bulge has the characteristics of a classical bulge sooner than those of a pseudobulge. Detailed abundance studies of bulge stars is a key to inv…
Na-O Anticorrelation and HB. VII. The chemical composition of first and second-generation stars in 15 globular clusters from GIRAFFE spectra
E. Carretta, A. Bragaglia, R. G. Gratton +12
We present abundances of Fe, Na, and O for 1409 red giant stars in 15 galactic globular clusters, derived from the homogeneous analysis of high resolution FLAMES/GIRAFFE spectra. C…
VLT-FLAMES Analysis of 8 giants in the Bulge Metal-poor Globular Cluster NGC 6522: Oldest Cluster in the Galaxy?
B. Barbuy, M. Zoccali, S. Ortolani +5
NGC 6522 has been the first metal-poor globular cluster identified in the bulge by W. Baade. Despite its importance, very few high resolution abundance analyses of stars in this cl…
Li-rich RGB stars in the Galactic Bulge
O. A. Gonzalez, M. Zoccali, L. Monaco +7
We present Lithium abundance determination for a sample of K giant stars in the galactic bulge. The stars presented here are the only 13 stars with detectable Lithium line (6767.18…
Pfleiderer2: identification of a new globular cluster in the Galaxy
Sergio Ortolani, Charles Bonatto, Eduardo Bica +1
We provide evidence that indicate the star cluster Pfleiderer 2, which is projected in a rich field, as a newly identified Galactic globular cluster. Since it is located in a crowd…
