M13 multiple stellar populations seen with the eyes of Strömgren photometry
A. Savino, D. Massari, A. Bragaglia +2
We present a photometric study of M13 multiple stellar populations over a wide field of view, covering approximately 6.5 half-light radii, using archival Isaac Newton Telescope obs…
3D motions in the Sculptor dwarf galaxy as a glimpse of a new era
D. Massari, M. A. Breddels, A. Helmi +3
The 3D motions of stars in small galaxies beyond our own are minute and yet they are crucial for our understanding of the nature of gravity and dark matter. Even for the dwarf gala…
Proper motions and structural parameters of the Galactic globular cluster M71
M. Cadelano, E. Dalessandro, F. R. Ferraro +4
By exploiting two ACS/HST datasets separated by a temporal baseline of ~7 years, we have determined the relative stellar proper motions (providing membership) and the absolute prop…
The power of teaming up HST and Gaia: the first proper motion measurement of the distant cluster NGC 2419
Davide Massari, Lorenzo Posti, Amina Helmi +2
Aims: We present the first measurement of the proper motion and orbit of the very distant and intriguing globular cluster NCG 2419. Methods: We have combined data from HST and Gaia…
