In the context of the Hubble Space Telescope UV Survey of Galactic globular clusters (GCs),
we derived high-precision, multi-band photometry to investigate the multiple stellar …

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 …

Due to their extreme helium abundance, the multiple stellar populations of the globular
cluster NGC 2808 have been widely investigated from a photometric, spectroscopic, and …

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 …

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

A number of scenarios for the formation of multiple populations in globular clusters (GCs)
predict that second generation (2G) stars form in a compact and dense subsystem …

Abstract The Hubble Space Telescope UV Legacy Survey of Galactic Globular Clusters is
providing a major breakthrough in our knowledge of globular clusters (GCs) and their stellar …

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 …

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 …
