Globular clusters (GCs) exhibit star-to-star variations in specific elements (eg, He, C, N, O,
Na, Al) that bear the hallmark of high-temperature H-burning. These abundance variations …

We review the multiple population (MP) phenomenon of globular clusters (GCs): ie, the
evidence that GCs typically host groups of stars with different elemental abundances and/or …

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 use high-precision photometry of red-giant-branch (RGB) stars in 57 Galactic globular
clusters (GCs), mostly from the 'Hubble Space Telescope (HST) UV Legacy Survey of …

In this paper we describe a new UV-initiative Hubble Space Telescope project (GO-13297)
that will complement the existing F606W and F814W database of the Advanced Camera for …

The oldest, most metal-poor stars in the Galactic halo and satellite dwarf galaxies present an
opportunity to explore the chemical and physical conditions of the earliest star-forming …

Globular clusters are large and dense agglomerate of stars. At variance with smaller clusters
of stars, they exhibit signs of some chemical evolution. At least for this reason, they are …

We investigate the Fe, C, N, O, Mg, Al, Si, K, Ca, Ce, and Nd abundances of 2283 red giant
stars in 31 globular clusters from high-resolution spectra observed in both the Northern and …

We present a new scheme for the classification of the in-situ and accreted globular clusters
(GCs). The scheme uses total energy E and z-component of the orbital angular momentum …

We explain the multiple populations recently found in the 'prototype'globular cluster (GC)
NGC 2808 in the framework of the asymptotic giant branch (AGB) scenario. The chemistry of …
