Stellar Population Astrophysics (SPA) with the TNG. Beyond the iron peak: Galactic evolution of molybdenum, ruthenium and zirconium through open clusters

Natalia Alvarez-Baena, Valentina D'Orazi, Christopher Sneden +11

Context: Open clusters serve as key laboratories for studying the chemical evolution of the Milky Way. In particular, leveraging these coeval groups of stars to study elements beyo…

Stellar Population Astrophysics (SPA) with the TNG. CNO abundances in 28 open clusters

Bruno Ćurjurić, Arnas Drazdauskas, Gražina Tautvaišienė +4

Aims. Our main aim with this work was to enlarge the pool of open clusters with determined carbon, nitrogen, and oxygen abundances in evolved giants to further advance chemical clo…

Stellar Population Astrophysics (SPA) with the TNG 23 IR elemental abundances of 114 giant stars in 41 Open Clusters

Shilpa Bijavara Seshashayana, Henrik Jönsson, Valentina D'Orazi +4

Open clusters have been extensively used as tracers of Galactic chemical evolution, as their constituent stars possess shared characteristics, including age, Galactocentric radius,…

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…

astro-ph.SR2024

Transferring spectroscopic stellar labels to 217 million Gaia DR3 XP stars with SHBoost

A. Khalatyan, F. Anders, C. Chiappini +14

In this paper, we explore the feasibility of using machine learning regression as a method of extracting basic stellar parameters and line-of-sight extinctions from spectro-photome…
