Three candidate double clusters in the LMC: truth or dare?
E. Dalessandro, A. Zocchi, A. L. Varri +6
The Large Magellanic Cloud (LMC) hosts a large number of candidate stellar cluster pairs. Binary stellar clusters provide important clues about cluster formation processes and the…
Modelling the Observed Stellar Mass Function and its Radial Variation in Galactic Globular Clusters
Jeremy J. Webb, Enrico Vesperini, Emanuele Dalessandro +3
We measure how the slope of the stellar mass function (MF) changes as a function of clustercentric distance in five Galactic globular clusters and compare to predict…
A complete census of emitters in NGC 6397
Cristina Pallanca, Giacomo Beccari, Francesco R. Ferraro +3
We used a dataset of archival Hubble Space Telescope images obtained through the F555W, F814W and F656N filters, to perform a complete search for objects showing emission in t…
The Optical Counterpart to the Accreting Millisecond X-ray Pulsar SAX J1748.9-2021 in the Globular Cluster NGC 6440
M. Cadelano, C. Pallanca, F. R. Ferraro +3
We used a combination of deep optical and Halpha images of the Galactic globular cluster NGC 6440, acquired with the Hubble Space Telescope, to identify the optical counterpart to…
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…
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…
