Hubble Space Telescope survey of Magellanic Cloud star clusters. Binaries among the split main sequences of NGC 1818, NGC 1850, and NGC 2164

F. Muratore, A. P. Milone, F. D'Antona +15

Nearly all star clusters younger than ~600 Myr exhibit extended main sequence turn offs and split main sequences (MSs) in their color-magnitude diagrams. Works based on both photom…

Internal Dynamics of Multiple Populations in 28 Galactic Globular Clusters: A Wide-Field study with Gaia and the Hubble Space Telescope

Giacomo Cordoni, Luca Casagrande, Antonino Milone +11

We present a detailed analysis of the internal dynamics of multiple stellar populations (MPs) in 28 Galactic Globular Clusters (GCs) across a wide field of view, extending from the…

A JWST project on 47 Tucanae. NIRSpec spectroscopy of multiple populations among M dwarfs

A. F. Marino, A. P. Milone, A. Renzini +12

We present the first spectroscopic estimates of the chemical abundance of M dwarf stars in a globular cluster (GC), namely 47 Tucanae. By exploiting NIRSpec on board the James Webb…

Exploring Simple-Population and Multiple-Population Globular Clusters in the Outer Galactic Halo using the Hubble Space Telescope

E. P. Lagioia, A. P. Milone, M. V. Legnardi +13

The pseudo two-color diagram, known as chromosome map (ChM), is a valuable tool for identifying globular clusters (GCs) that consist of single or multiple stellar populations (MPs)…

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…

On the original composition of the gas forming first-generation stars in clusters: insights from HST and JWST

M. V. Legnardi, A. P. Milone, G. Cordoni +8

Globular cluster (GC) stars composed of pristine material (first-generation, 1G, stars) are not chemically homogeneous, as they exhibit extended sequences in the "Chromosome Map" (…

Early-phase simultaneous multiband observations of the Type II supernova SN 2024ggi with Mephisto

Xinlei Chen, Brajesh Kumar, Xinzhong Er +24

We present early-phase good-cadence (hour-to-day) simultaneous multiband ( and bands) imaging of the nearby supernova SN~2024ggi, which exploded in the nearby galaxy, NG…

A JWST project on 47 Tucanae. Overview, photometry and early spectroscopic results of M dwarfs, and observation of brown dwarfs

A. F. Marino, A. P. Milone, M. V. Legnardi +14

The James Webb Space Telescope (JWST) observations have been demonstrated to be efficient in detecting globular clusters' (GCs) multiple stellar populations in the low mass regime…
