Tracing the early Milky Way thin disc with the Gaia-ESO Survey
Carlos Viscasillas Vázquez, Sofia Randich, Riano Escate Giribaldi +3
The origin of metal-poor stars on thin-disc-like orbits remains an open question in Galactic archaeology and provides important constraints on the earliest phases of Milky Way disc…
The T-GEX project. I. Stealth UV-bright Sun-like stars in the Galaxy as candidate contributors to the UV upturn
M. L. L. Dantas, D. Beltrán, R. E. Giribaldi +3
The authors created a catalog of 37 Sun-like stars by combining Gaia-ESO spectroscopy, Gaia DR3 astrometry, GALEX UV photometry, and infrared data, and identified UV‑bright sub‑pop…
HRMOS: A High-Resolution Multi-Object Spectrograph for the VLT
Laura Magrini, Thomas Bensby, Sofia Randich +174
This White Paper presents the scientific rationale and instrument concept for HRMOS (High-Resolution Multi-Object Spectrograph), a next-generation instrument proposed for the ESO V…
Observational Signatures and Constraints on the Intermediate Neutron-Capture Process. The Case of the CEMP star TYC 6044-714-1 (RAVE J094921.8-161722)
Riano E. Giribaldi, Diego Vescovi, Laura Magrini +6
Observational abundances of CEMP stars with patterns in between those produced by the rapid and slow nucleosynthesis processes (CEMP-rs stars) are currently invoked as evidence of…
The nucleosynthesis of Ba in the Early Universe. Constraints from elemental abundances and isotopic ratios
Riano E. Giribaldi, Marco Palla, Laura Magrini +6
The [Ba/Eu] abundance ratio is commonly adopted as a tracer of the relative contributions of the slow (s) and rapid (r) neutron-capture processes. However, at [Fe/H] < -2 dex, Ba c…
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 --…
