A kinematic view of NGC 1261: structural parameters, internal dispersion, absolute proper motion and Blue Straggler Stars
S. Raso, M. Libralato, A. Bellini +8
We constructed a Hubble Space Telescope (HST) astro-photometric catalog of the central region of the Galactic globular cluster NGC 1261. This catalog, complemented with Gaia DR2 da…
Digging for relics of the past: the ancient and obscured bulge globular cluster NGC6256
Mario Cadelano, Sara Saracino, Emanuele Dalessandro +5
We used a set of moderately-deep and high-resolution optical observations obtained with the Hubble Space Telescope to investigate the properties of the stellar population in the he…
Star density profiles of six old star clusters in the Large Magellanic Cloud
B. Lanzoni, F. R. Ferraro, E. Dalessandro +7
We used resolved star counts from Hubble Space Telescope images to determine the center of gravity and the projected density profiles of 6 old globular clusters in the Large Magell…
A family picture: tracing the dynamical path of the structural properties of multiple populations in globular clusters
E. Dalessandro, M. Cadelano, E. Vesperini +6
We studied the spatial distributions of multiple stellar populations (MPs) in a sample of 20 globular clusters (GCs) spanning a broad range of dynamical ages. The differences betwe…
Light element variations within the different age-metallicity populations in the nucleus of the Sagittarius dwarf
Alison Sills, Emanuele Dalessandro, Mario Cadelano +2
The cluster M54 lies at the centre of the Sagittarius dwarf spheroidal galaxy, and therefore may be the closest example of a nuclear star cluster. Either in-situ star formation, in…
An extremely low-mass He white dwarf orbiting the millisecond pulsar J1342+2822B in the globular cluster M3
M. Cadelano, F. R. Ferraro, A. G. Istrate +3
We report on the discovery of the companion star to the millisecond pulsar J1342+2822B in the globular cluster M3. We exploited a combination of near-ultraviolet and optical observ…
