The C+N+O abundance of Omega Centauri giant stars: implications on the chemical enrichment scenario and the relative ages of different stellar populations
A. F. Marino, A. P. Milone, G. Piotto +7
We present a chemical-composition analysis of 77 red-giant stars in Omega Centauri. We have measured abundances for carbon and nitrogen, and combined our results with abundances of…
The ACS Survey of Galactic Globular Clusters. XII. Photometric Binaries along the Main-Sequence
A. P. Milone, G. Piotto, L. R. Bedin +15
The fraction of binary stars is an important ingredient to interpret globular cluster dynamical evolution and their stellar population. We investigate the properties of main-sequen…
The VISIR@VLT Mid-IR view of 47Tuc: A further step in solving the puzzle of RGB mass loss
Y. Momany, I. Saviane, A. Smette +5
There is an ongoing debate regarding the onset luminosity of dusty mass loss in population-II red giant stars. In this paper we present VISIR@VLT MIR 8.6 micron imaging of 47Tuc, c…
A Double Main Sequence in the Globular Cluster NGC 6397
A. P. Milone, A. F. Marino, G. Piotto +5
High-precision multi-band HST photometry reveals that the main sequence (MS) of the globular cluster NGC 6397 splits into two components, containing ~30% and ~70% of the stars. Thi…
Multiple stellar populations in 47 Tucanae
A. P. Milone, G. Piotto, L. R. Bedin +16
We use Hubble Space Telescope (HST) and ground-based imaging to study the multiple populations of 47 Tuc, combining high-precision photometry with calculations of synthetic spectra…
The ACS Survey of Galactic Globular Clusters XI: The Three-Dimensional Orientation of the Sagittarius Dwarf Spheroidal Galaxy and its Globular Clusters
Michael H. Siegel, Steven R. Majewski, David R. Law +13
We use observations from the ACS study of Galactic globular clusters to investigate the spatial distribution of the inner regions of the disrupting Sagittarius dwarf spheroidal gal…
