Lost and found: evidence of Second Generation stars along the Asymptotic Giant Branch of the globular cluster NGC 6752
E. Lapenna, C. Lardo, A. Mucciarelli +7
We derived chemical abundances for C, N, O, Na, Mg and Al in 20 asymptotic giant branch (AGB) stars in the globular cluster NGC 6752. All these elements (but Mg) show intrinsic sta…
Terzan 5: a pristine fragment of the Galactic Bulge?
Davide Massari, F. R. Ferraro, A. Mucciarelli +3
Terzan 5 is a stellar system located in the inner Bulge of the Galaxy and has been historically catalogued as a globular cluster. However, recent photometric (Ferraro et al. 2009)…
Density and kinematic cusps in M54 at the heart of the Sagittarius dwarf galaxy: evidence for a 10^4 M_sun Black Hole?
R. Ibata, M. Bellazzini, S. C. Chapman +8
We report the detection of a stellar density cusp and a velocity dispersion increase in the center of the globular cluster M54, located at the center of the Sagittarius dwarf galax…
Near-Infrared photometry of four metal-rich Bulge globular clusters: NGC6304, NGC6569, NGC6637, NGC6638
E. Valenti, L. Origlia, F. R. Ferraro
We present high-quality near-Infrared photometry of four Bulge metal-rich globular clusters, namely: NGC 6304, NGC 6569, NGC 6637 and NGC 6638. By using the observed Colour-Magnitu…
A near-infrared spectroscopic screening of the red giant populations in omega Centauri
L. Origlia, F. R. Ferraro, M. Bellazzini +1
Near-infrared spectra of 21 giants in omega Centauri, spanning the whole range of metallicities observed in this cluster, are presented. This work is part of a coordinated photomet…
Age as the Second Parameter in NGC 288/NGC 362? II. The Horizontal Branch Revisited
M. Catelan, M. Bellazzini, W. B. Landsman +3
We revisit the "second parameter" pair of globular clusters NGC 288/NGC 362 on the basis of theoretical models for red giant branch (RGB) and horizontal branch (HB) stars. The resu…
