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…
Asteroseismic ages for 17,000 stars in Kepler, K2 and TESS
Emma Willett, Andrea Miglio, Saniya Khan +9
The availability of asteroseismic constraints for tens of thousands of red giant (RG) stars has opened the door to robust age estimates, enabling time-resolved studies of different…
Co-evolution of the Milky Way high- and low-α sequences with chemical evolution models
V. Grisoni, E. Spitoni, F. Matteucci
Observational data have revealed a clear dichotomy in the [α/Fe] vs. [Fe/H] diagram of the Milky Way thick and thin disc stars. Many recent studies have shown evidences of a co-ev…
Milky Way disc & Bulge in situ populations: ESO white paper - Expanding horizons call
M. Bergemann, G. Kordopatis, G. Casali +11
The formation and evolution of the Milky Way's disc, bar, and bulge remain fundamentally limited by the lack of a contiguous, Galaxy-wide, high-precision chemo-dynamical map. Key o…
Fluorine Evolution in the Galactic Halo
Valeria Grisoni, Federico Rizzuti, Gabriele Cescutti
The chemical evolution of fluorine is still a matter of debate in Galactic archaeology, especially at low metallicities, where it is particularly challenging to obtain the correspo…
Tracing the Milky Way: Calibrating chemical ages with high-precision Kepler data
G. Casali, J. Montalbà n, A. Miglio +10
Chemical clocks offer a powerful tool for estimating stellar ages from spectroscopic surveys. We present a new detailed spectroscopic analysis of 68 Kepler red giant stars to provi…
