Tracing the Early Milky Way with Globular Clusters: The Diagnostic Power of Neutron-Capture Elements
J. Schiappacasse-Ulloa, L. Berni, S. Lucatello +3
Globular clusters (GCs) are fundamental tracers of the early assembly of the Milky Way (MW). They formed in diverse environments -- including both our Galaxy and dwarf galaxies --…
LRPayne: Stellar parameters and abundances from low-resolution spectra
Nagaraj Vernekar, Lorenzo Spina, Sara Lucatello +4
Aims. This paper introduces LRPayne, a novel algorithm designed for the efficient determination of stellar parameters and chemical abundances from low-resolution optical spectra, w…
Deep chemical tagging -- Identifying open clusters and moving groups in chemical space with graph attention networks
Lorenzo Spina, Milan Quandt Rodriguez, Laura Magrini +3
Reconstructing the formation history of the Milky Way is hindered by stellar migration, which erases kinematic birth signatures. In contrast, stellar chemical abundances remain sta…
Stellar Population Astrophysics (SPA) with the TNG: NLTE atmospheric parameters and abundances of giant stars in 33 Open Clusters
M. Dal Ponte, V. D'Orazi, A. Bragaglia +11
Open clusters serve as important tools for accurately studying the chemical evolution of the Milky Way. By combining precise chemical data from high-resolution spectra with informa…
Signatures of planets and Galactic subpopulations in solar analogs. Precise chemical abundances with neural networks
Giulia Martos, Jorge Meléndez, Lorenzo Spina +1
The aim of this work is to obtain precise atmospheric parameters and chemical abundances automatically for solar twins and analogs to find signatures of exoplanets, as well as to a…
Neutron-Capture Element Signatures in Globular Clusters: Insights from the Gaia-ESO Survey
J. Schiappacasse-Ulloa, L. Magrini, S. Lucatello +8
Globular clusters (GCs) are key to understanding the formation and evolution of our Galaxy. While the abundances of light and Fe-peak elements in GCs have been widely studied, inve…
