The internal kinematics of NGC 2808 and its multiple populations
M. Griggio, A. Bellini, F. I. Aros +10
We use new HST observations coupled with archival data spanning a total temporal baseline of 17 years to study the internal kinematics of the multiple populations in the globular c…
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…
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…
The double Blue Straggler sequence in NGC2173: yes, a field contamination artefact!
E. Dalessandro, F. R. Ferraro, N. Bastian +3
Li et al. (2018a; Li18a) claimed that the young stellar cluster NGC2173 in the Large Magellanic Cloud (LMC) harbours a bifurcated sequence of blue straggler stars (BSSs), similar t…
The double Blue Straggler sequence in NGC2173: a field contamination artefact
E. Dalessandro, F. R. Ferraro, N. Bastian +3
Here we discuss the case of the double Blue Straggler Star (BSS) sequence recently detected in the young stellar cluster NGC 2173 in the Large Magellanic Cloud by Li et al (2018).…
The Peculiar Radial Distribution of Multiple Populations in the massive globular cluster M80
E. Dalessandro, M. Cadelano, E. Vesperini +7
We present a detailed analysis of the radial distribution of light-element multiple populations (LE-MPs) in the massive and dense globular cluster M80 based on the combination of U…
The "UV-route" to search for Blue Straggler Stars in Globular Clusters: first results from the HST UV Legacy Survey
S. Raso, F. R. Ferraro, E. Dalessandro +4
We used data from the HST UV Legacy Survey of Galactic Globular Clusters to select the Blue Straggler Star (BSS) population in four intermediate/high density systems (namely NGC 28…
