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…
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…
Size diversity of old Large Magellanic Cloud clusters as determined by internal dynamical evolution
F. R. Ferraro, B. Lanzoni, E. Dalessandro +6
The distribution of size as a function of age observed for star clusters in the Large Magellanic Cloud (LMC) is very puzzling: young clusters are all compact, while the oldest syst…
High-resolution extinction map in the direction of the bulge globular cluster NGC 6440
Cristina Pallanca, Francesco R. Ferraro, Barbara Lanzoni +3
We used optical images acquired with the UVIS channel of the Wide Field Camera 3 on board of the Hubble Space Telescope to construct the first high-resolution extinction map in the…
Spectral Energy Distribution of Blue Stragglers in the core of 47 Tucanae
S. Raso, C. Pallanca, F. R. Ferraro +8
We have constructed the Spectral Energy Distributions (SEDs) of a sample of Blue Straggler Stars (BSSs) in the core of the globular cluster 47 Tucanae, taking advantage of the larg…
Discovery of a double Blue Straggler sequence in M15: new insight into the core-collapse process
Giacomo Beccari, Francesco R. Ferraro, Emanuele Dalessandro +8
In this paper we report on the discovery of a double blue straggler star (BSS) sequence in the core of the core-collapsed cluster M15 (NGC 7078). We performed a detailed photometri…
