The stellar to sub-stellar masses transition in 47 Tuc
C. Ventura, M. Tailo, P. Ventura +4
Context: The study of the Globular Cluster 47 Tuc offers the opportunity to shed new light on the debated issue on the presence of multiple populations in Globular Clusters, as rec…
Tracing ωCentauri's origins: Spatial and chemical signatures of its formation history
E. Dondoglio, A. P. Milone, A. F. Marino +8
ω}Centauri (ωCen) is the most enigmatic Galactic globular cluster (GC), with unmatched chemical complexity. We combine photometric and spectroscopic catalogs to identify its distin…
The Small Magellanic Cloud through the lens of the James Webb Space Telescope : binaries and mass function within the galaxy outskirts
M. V. Legnardi, F. Muratore, A. P. Milone +8
The stellar initial mass function (IMF) and the fraction of binary systems are fundamental ingredients that govern the formation and evolution of galaxies. Whether the IMF is unive…
Dating N loud AGNs at high redshift: GS3073 as a snapshot of wCen like evolution of a nuclear star cluster
F. D'Antona, P. Ventura, A. F. Marino +8
In this paper we address two major questions raised by recent James Webb Space Telescope observations of the young Universe, namely: 1) what are the seed initial masses, and how ra…
Inferring the efficiency of convective-envelope overshooting in Red Giant Branch stars
Lorenzo Briganti, Marco Tailo, Edoardo Ceccarelli +6
The understanding of mixing processes in stars is crucial for improving our knowledge of the chemical abundances in stellar photospheres and of their variation with evolutionary ph…
A study of Andromeda to improve our knowledge on the evolution and dust production by AGB stars
Claudio Gavetti, Paolo Ventura, Flavia Dell'Agli +4
We study the AGB population of the galaxy M31, based on available HST and Spitzer data, to characterize the individual sources in terms of mass, metallicity and formation epoch of…
