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…
New perspective on the multiple population phenomenon in Galactic globular clusters from a wide-field photometric survey

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

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" (…
The metallicity variations along the chromosome maps: The Globular Cluster 47 Tucanae
A. F. Marino, A. P. Milone, E. Dondoglio +11
The "chromosome maps" (ChMs) of globular clusters (GCs) have revealed that these ancient structures are not homogeneous in metallicity in various ways, and in different natures. Th…
