Why the Northern Hemisphere Needs a 30-40 m Telescope and the Science at Stake: Resolved Stellar Populations Studies in M31 and its Satellites
C. Gallart, E. Fernández-Alvar, A. B. A. Queiroz +48
A 30 m class optical/near-IR telescope in the Northern Hemisphere, equipped for diffraction-limited imaging and high-resolution, multi-object spectroscopy of faint stars, would ena…
3D extinction maps of the Milky Way disc from Gaia GSP-Spec parameters
M. Barbillon, A. Recio-Blanco, P. de Laverny +1
3D maps of interstellar dust are crucial for understanding the structure of the Milky Way interstellar medium to apply correction to astrophysical observations affected by dust. We…
The AMBRE Project: Line-broadening and stellar rotation of ESO/FEROS archived spectra
F. Bado, P. de Laverny, Z. Kam +3
Stellar rotation is a fundamental parameter in stellar studies. However, large homogeneous catalogues of rotational velocities derived from high-resolution stellar spectra are stil…
The Great Wave: Evidence of a large-scale vertical corrugation propagating outwards in the Galactic disc
E. Poggio, S. Khanna, R. Drimmel +6
We analyse the three-dimensional structure and kinematics of two samples of young stars in the Galactic disc, containing respectively young giants (17000 stars out to he…
Signatures of simulated spiral arms on radial actions
P. A. Palicio, A. Recio-Blanco, T. Tepper-Garcia +7
Among the various implications of the spiral arms, it has been observed in the Milky Way disc that the distribution of radial actions from the Gaia Data Release 3 exhibits structur…
A comprehensive Gaia view of ellipsoidal and rotational red giant binaries
Camila Navarrete, Alejandra Recio-Blanco, Patrick de Laverny +1
The latest Gaia Focused Product Release (FPR) provided variability information for 1000 long-period red giant binaries, the largest sample to date of this binary type having…
