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 --…
Mapping the Ages of Stars with Chemistry
Carlos Viscasillas Vázquez, Giada Casali, Laura Magrini +11
Chemical clocks, based on age-sensitive stellar abundance ratios, offer a powerful and scalable approach to reconstruct the formation history of the Milky Way. This white paper out…
Distinct barium isotope ratios in CEMP-s and CEMP-rs stars
T. M. Sitnova, L. I. Mashonkina, A. M. Romanovskaya +2
We present a spectroscopic analysis of ten carbon enhanced metal-poor (CEMP) stars of type CEMP-s and CEMP-rs and determine their NLTE abundances of Ba and Eu, as well as the fract…
Barium isotopic ratios in metal-poor stars: calibrating the method with globular clusters
Riano E. Giribaldi, Laura Magrini, Jose Schiappacasse-Ulloa +2
Identifying the nucleosynthesis processes behind heavy-element enrichment in stellar atmospheres is challenging. It typically relies on comparing observed abundance-to-iron ratios…
How homogeneous was the chemical enrichment of the Milky Way 13 gigayears ago?
Riano E. Giribaldi, Laura Magrini, Martina Rossi +3
We reanalyze the chemical composition of the metal-poorest tail of the Galactic halo using highly accurate atmospheric parameters Giribaldi et al. (2021, 2023) and cutting-edge 3D…
Exploring substructures in the Milky Way halo Neural networks applied to Gaia and APOGEE DR 17
L. Berni, L. Spina, L. Magrini +3
The identification of stellar structures in the Galactic halo, including stellar streams and merger remnants, often relies on the dynamics of their constituent stars. However, this…
The metal-poorest tail of the Galactic halo: hypothesis on its origin from precise spectral analysis
Riano E. Giribaldi, Laura Magrini, Martina Rossi +3
The origin of the Galactic halo is one of the fundamental topics linking the study of galaxy formation and evolution to cosmology. We aim at deriving precise and accurate stellar p…
