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 …

Abstract The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters
(GCs) has investigated GCs and their stellar populations. In previous papers of this series …

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 …

In this paper, we present the astrophotometric catalogues of 56 globular clusters and one
open cluster. Astrometry and photometry are mainly based on images collected within the …

The majority of Galactic globular clusters (GCs) contain multiple stellar populations
displaying specific chemical abundance variations. In particular, GCs generally contain a …

We present high-precision multiband photometry for the globular cluster (GC) M2. We
combine the analysis of the photometric data obtained from the Hubble Space Telescope …

Recent work, based on data from the Hubble Space Telescope (HST) UV Legacy Survey of
Galactic Globular Clusters (GCs), has revealed that all the analysed clusters host two groups …

In this study we present the first results from multi-wavelength Hubble Space Telescope
(HST) observations of the Galactic globular cluster (GC) NGC 2808 as an extension of the …

We build on the evidence provided by our Legacy Survey of Galactic globular clusters (GC)
to submit to a crucial test four scenarios currently entertained for the formation of multiple …

We make use of the 'Next Generation'model atmospheres of Allard et al. and Hauschildt,
Allard & Baron to compute theoretical models for low-and very-low-mass stars for selected …
