Modelling s-process chemical clocks: insights from high-precision Kepler data
G. Casali, M. Molero
We present Galactic chemical evolution (GCE) models for the chemical clocks [Zr/Ti] and [Ce/Ti], tracing first- and second-peak s-process nucleosynthesis, and compare them with a h…
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…
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…
Rubidium Abundances in Cool Giants from High-Resolution H-band Spectra: A New Diagnostic for Galactic Chemical Evolution
Nils Ryde, Jess Kocher, Govind Nandakumar +6
The Galactic Center and inner disk of the Milky Way contain complex stellar populations obscured by heavy dust extinction. To study their chemical composition, high-resolution near…
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…
