We have determined masses, stellar mass functions, and structural parameters of 112 Milky
Way globular clusters by fitting a large set of N-body simulations to their velocity dispersion …

We have determined the masses and mass-to-light ratios of 50 Galactic globular clusters by
comparing their velocity dispersion and surface brightness profiles against a large grid of …

Context. Blue straggler stars are exotic objects present in all stellar environments whose
nature and formation channels are still partially unclear. They seem to be particularly …

We used an appropriate combination of high-resolution Hubble Space Telescope
observations and wide-field, ground-based data to derive the radial stellar density profiles of …

Context. The particularly abundant presence of blue straggler stars (BSS) in Galactic open
clusters offers favorable conditions for detailed studies on the statistical properties and the …

Binary stars play a major role in determining the dynamic evolution of star clusters. We used
images collected with the Hubble Space Telescope to study fourteen star clusters of the …

Massive globular clusters (GCs) contain at least two generations of stars with slightly
different ages and clearly distinct light element abundances. The Na-O anticorrelation is the …

We used resolved star counts from Hubble Space Telescope (HST) images to determine the
center of gravity and the projected density profiles of six old globular clusters (GCs) in the …

We used a combination of Hubble Space Telescope and ground-based data to probe the
dynamical state of the low-mass Galactic globular cluster NGC 6101. We have rederived the …

Context. Globular clusters (GCs) associated with the Sagittarius dwarf spheroidal galaxy
(Sgr dSph) have evolved under the gravitational potential of both Sgr dSph and the Milky …
