WST -- Wide-field Spectroscopic Telescope: The Next Leap in Wide-field Spectroscopy
Roland Bacon, Olga Bellido, Philippe Dierickx +53
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…
