The oldest low- thin disc stars
Riano E. Giribaldi, Laura Magrini, Marco Palla +1
The formation pathway of the -poor Milky Way thin disc remains under debate. The latest observational data indicates the presence of comparable numbers of old stars in both the…
WST -- Wide-field Spectroscopic Telescope: The Next Leap in Wide-field Spectroscopy
Roland Bacon, Olga Bellido, Philippe Dierickx +52
The Wide-field Spectroscopic Telescope (WST) is a concept for a dedicated 12-m spectroscopic survey facility designed to address some of the most important questions in astrophysic…
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…
The effects of yields from binary massive stars as functions of metallicity
E. Pepe, E. Spitoni, F. Matteucci +1
Massive stars in binary systems that undergo mass transfer during their lifetime have a different evolution from that of single stars, possibly affecting their chemical yields. Whi…
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…
The chemical DNA of the Magellanic Clouds VI. Origin and evolution of neutron-capture elements in the SMC
Marco Palla, Alessio Mucciarelli, Donatella Romano +2
Context. In the context of galactic archaeology, the study of the Small Magellanic Cloud (SMC) is of crucial importance, as it represents a unique opportunity to study a nearby mas…
Evidence for multiple crossings and stripping of Gaia-Enceladus/Sausage across the Milky Way
L. Berni, M. Palla, L. Magrini +1
The accretion of Gaia-Enceladus/Sausage (GES) onto the Milky Way (MW) is one of the most prominent features of the Galactic halo revealed by the combination of the Gaia satellite a…
The chemical DNA of the Magellanic Clouds V. R-process dominates neutron capture elements production in the oldest SMC stars
Lorenzo Santarelli, Marco Palla, Alessio Mucciarelli +4
We present the chemical abundances of Fe, alpha- and neutron-capture elements in 12 metal-poor Small Magellanic Cloud (SMC) giant stars, observed with the high-resolution spectrogr…
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…
The chemical DNA of the Magellanic Clouds IV. Unveiling extreme element production: the Eu abundance in the Small Magellanic Cloud
Samuele Anoardo, Alessio Mucciarelli, Marco Palla +3
In this study we investigate the chemical enrichment of the rapid neutron-capture process in the Small Magellanic Cloud (SMC). We measure [Eu/Fe] abundance ratios in 209 giant star…
A Walk on the Retrograde Side (WRS) project. II. Chemistry to disentangle in situ and accreted components in Thamnos
E. Ceccarelli, D. Massari, M. Palla +3
We present the results of the first systematic and dedicated high-resolution chemical analysis of the Thamnos substructure, a candidate relic of the process of hierarchical merger…
Shaping Galactic Habitability: the impact of stellar migration and gas giants
E. Spitoni, M. Palla, L. Magrini +9
In exoplanet research, the focus is increasingly on identifying Earth analogs, planets similar in density and habitability potential. As the number of rocky exoplanets grows, paral…
Europium, we have a problem. Modelling r-process enrichment across Local Group galaxies
Marco Palla, Marta Molero, Donatella Romano +1
Context: Europium (Eu) serves as a crucial tracer to understand the origin of rapid neutron-capture process (r-process) elements. An extensive effort was made in the last decade to…
