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 …

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 …

Gaia Data Release 3 provides novel flux-calibrated low-resolution spectrophotometry for≃
220 million sources in the wavelength range 330 nm≤ λ≤ 1050 nm (XP spectra). Synthetic …

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 Galactic Archaeology with HERMES (GALAH) survey is a large high-resolution
spectroscopic survey using the newly commissioned High Efficiency and Resolution Multi …

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 …

We present a model for the concurrent formation of globular clusters (GCs) and
supermassive stars (SMSs,≳ 103 M⊙) to address the origin of the HeCNONaMgAl …

Ages have been derived for 55 globular clusters (GCs) for which Hubble Space Telescope
Advanced Camera for Surveys photometry is publicly available. For most of them, the …

We present wide-field, ground-based Johnson–Cousins UBVRI photometry for 48 Galactic
globular clusters based on about 90 000 public and proprietary images. The photometry is …

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 …
