The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters. II. The seven stellar populations of NGC7089 (M2)
A. P. Milone, A. F. Marino, G. Piotto +17
We present high-precision multi-band photometry for the globular cluster (GC) M2. We combine the analysis of the photometric data obtained from the Hubble Space Telescope UV Legacy…
Observing multiple stellar populations with FORS2@VLT - Main sequence photometry in outer regions of NGC 6752, NGC 6397, and NGC 6121 (M 4)
D. Nardiello, A. P. Milone, G. Piotto +3
We present the photometric analysis of the external regions of three Galactic Globular Clusters: NGC 6121, NGC 6397 and NGC 6752. The main goal is the characterization of the multi…
A bag of tricks: Using proper motions of Galactic stars to identify the Hercules ultra-faint dwarf galaxy members
M. Fabrizio, G. Raimondo, E. Brocato +13
Hercules is the prototype of the ultra-faint dwarf (UFD) galaxies. To date, there are still no firm constraints on its total luminosity, due to the difficulty of disentangling Herc…
The halo+cluster system of the Galactic globular cluster NGC1851
A. F. Marino, A. P. Milone, D. Yong +17
NGC1851 is surrounded by a stellar component that extends more than ten times beyond the tidal radius. Although the nature of this stellar structure is not known, it has been sugge…
M4 Core Project with HST - III. Search for variable stars in the primary field
V. Nascimbeni, L. R. Bedin, D. C. Heggie +14
We present the results of a photometric search for variable stars in the core of the Galactic globular cluster M4. The input data are a large and unprecedented set of deep Hubble S…
The M4 Core Project with HST -- II. Multiple Stellar Populations at the Bottom of the Main Sequence
A. P. Milone, A. F. Marino, L. R. Bedin +15
The M4 Core Project with HST is designed to exploit the Hubble Space Telescope to investigate the central regions of M4, the Globular Cluster closest to the Sun. In this paper we c…
