Euclid: The convective-transition gap of 47 Tuc
M. Libralato, M. Griggio, R. Gerasimov +140
We report the first detection of the `convective-transition gap' (also known as `M-dwarf gap') in the globular cluster 47 Tuc (NGC 104) thanks to Euclid data. This feature, linked…
Euclid: Quick Data Release (Q1) -- Ultracool dwarfs in the Euclid Deep Fields
A. Mohandasan, R. L. Smart, C. Reylé +180
Ultracool dwarfs (UCDs) encompass the lowest-mass stars and brown dwarfs at the substellar boundary. These intrinsically faint objects are challenging to detect, but the wide cover…
A JWST project on 47 Tucanae. Binaries among multiple populations
A. P. Milone, A. F. Marino, M. Bernizzoni +25
Almost all globular clusters (GCs) contain multiple populations consisting of stars with varying helium and light-element abundances. These populations include first-population sta…
Euclid: Quick Data Release (Q1) -- A photometric search for ultracool dwarfs in the Euclid Deep Fields
M. Žerjal, C. Dominguez-Tagle, N. Vitas +178
We present a catalogue of 5306 new ultracool dwarf (UCD) candidates in the three Euclid Deep Fields in the Q1 data release. They range from late M to late T dwarfs, and include 120…
Mass loss along the red giant branch of the intermediate stellar populations in NGC6752 and NGC2808
M. Tailo, A. P. Milone, A. F. Marino +15
The morphology of the Horizontal Branch (HB) in Globular Clusters (GC) is among the early evidences that they contain multiple populations of stars. Indeed, the location of each st…
Spectro-Photometry and Radial Distribution of Multiple Stellar Populations in Globular Clusters from Gaia XP Spectra
V. J. Mehta, A. P. Milone, L. Casagrande +14
Understanding the formation of multiple populations in globular clusters (GCs) represents a challenge for stellar population studies. Nevertheless, the outermost cluster regions, l…
Photometric Binaries in 14 Magellanic Cloud Star Clusters
Anjana Mohandasan, Antonino P. Milone, Giacomo Cordoni +7
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 Magellanic Clouds s…
Hubble Space Telescope survey of Magellanic Cloud star clusters. UV-dim stars in young clusters
A. P. Milone, G. Cordoni, A. F. Marino +11
Young and intermediate-age star clusters of both Magellanic Clouds exhibit complex color-magnitude diagrams. In addition to the extended main-sequence turn-offs (eMSTOs), commonly…
Multiple Stellar Populations in Metal-Poor Globular Clusters with JWST: a NIRCam view of M92
Tuila Ziliotto, Antonino P. Milone, Anna F. Marino +10
Recent work on metal-intermediate globular clusters (GCs) with [Fe/H]= and has illustrated the theoretical behavior of multiple populations in photometric diagrams ob…
Photometric binaries, mass functions, and structural parameters of 78 Galactic open clusters
Giacomo Cordoni, Antonino P. Milone, Anna F. Marino +8
Binary stars play a crucial role in our understanding of the formation and evolution of star clusters and their stellar populations. We use Gaia Data Release 3 to homogeneously ana…
Multiple Stellar Populations in Globular Clusters with JWST: a NIRCam view of 47 Tucanae
A. P. Milone, A. F. Marino, A. Dotter +11
We use images collected with the near-infrared camera (NIRCam) on board the James Webb Space Telescope and with the Hubble Space Telescope (HST) to investigate multiple populations…
Hubble Space Telescope survey of Magellanic Cloud star clusters. Photometry and astrometry of 113 clusters and early results
A. P. Milone, G. Cordoni, A. F. Marino +29
In the past years, we have undertaken an extensive investigation of LMC and SMC star clusters based on HST data. We present photometry and astrometry of stars in 101 fields observe…
NGC1818 unveils the origin of the extended main-sequence turn-off in young Magellanic Clouds clusters
Giacomo Cordoni, Antonino P. Milone, Anna F. Marino +8
The origin of young star clusters represents a major challenge for modern stellar astrophysics. While stellar rotation partially explains the colour spread observed along main-sequ…
Survey of multiple populations in globular clusters among very low-mass stars
E. Dondoglio, A. P. Milone, A. Renzini +14
Recent work has shown that NIR Hubble Space Telescope (HST) photometry allows us to disentangle multiple populations (MPs) among M dwarfs of globular clusters (GCs) and investigate…
Mass loss law for red giant stars in simple population globular clusters
M. Tailo, A. P. Milone, E. P. Lagioia +12
The amount of mass lost by stars during the red-giant branch (RGB) phase is one of the main parameters to understand and correctly model the late stages of stellar evolution. Never…
