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…
HRMOS: a very high-resolution, multi-object spectrograph for the ESO VLT
Andrea Bianco, Sofia Randich, Emma Fernandez Alvar +7
HRMOS (High-Resolution Multi-Object Spectrograph) is a proposed new instrument for the ESO Very Large Telescope (VLT) developed in the context of the ESO VLT Beyond 2030 call. It i…
Sustainability as a design parameter in the early development of the Wide-field Spectroscopic Telescope
L. Fréour, E. Burtin, R. Bacon +13
The proposed Wide-field Spectroscopic Telescope, a next-generation telescope facility with a 12-meter primary mirror that may be operational in the 2040s, is integrating sustainabl…
X-shooter spectroscopy of young stars with disks. The TW Hydrae association as a probe of the final stages of disk accretion
L. Venuti, B. Stelzer, J. M. Alcalá +9
We investigate ongoing accretion activity in young stars in the TW Hydrae association (TWA, ~8-10 Myr), an ideal target to probe the final stages of disk accretion down to brown dw…
The Gaia-ESO survey: impact of extra-mixing on C- and N-abundances of giant stars
N. Lagarde, C. Reylé, A. C. Robin +30
The GES survey using FLAMES at the VLT has obtained high-resolution UVES spectra for a large number of giant stars, allowing a determination of the abundances of the key chemical e…
