We discuss the observational properties of a special class of objects (the so-called “Blue
Straggler Stars”, BSSs) in the framework of using this stellar population as probe of the …

In the context of a project aimed at characterizing the properties of the so-called Bulge Fossil
Fragments (the fossil remnants of the bulge formation epoch), here we present the first …

We used a combination of high-resolution optical images acquired with the Hubble Space
Telescope and near-IR wide-field data to investigate the stellar density profile and the …

The formation and evolutionary processes of galaxy bulges are still unclear, and the
presence of young stars in the bulge of the Milky Way is largely debated. We recently …

Blue stragglers are anomalously luminous core hydrogen-burning stars formed through
mass-transfer in binary/triple systems and stellar collisions. Their physical and evolutionary …

Abstract High-resolution Hubble Space Telescope optical observations have been used to
analyze the stellar population and the structure of the poorly investigated bulge globular …

We have used the" dynamical clock" to measure the level of dynamical evolution reached by
three Galactic globular clusters (namely, NGC 3201, NGC 6316, and NGC 6440). This is an …

The study of stellar dynamics is experiencing an exciting new wave of interest thanks to
observational campaigns and the ready availability of powerful computers. Whilst its …

We study an intermediate-age open cluster (OC) NGC 2506 using the ASTROSAT/UVIT data
and other archival data. We identified 2175 cluster members using a machine learning …
