The cerium content of the Milky Way as revealed by Gaia DR3 GSP-Spec abundances
G. Contursi, P. de Laverny, A. Recio-Blanco +12
The recent Gaia Third Data Release contains a homogeneous analysis of millions of high-quality Radial Velocity Spectrometer (RVS) stellar spectra by the GSP-Spec module. This led t…
Stellar ages, masses, extinctions and orbital parameters based on spectroscopic parameters of Gaia DR3
G. Kordopatis, M. Schultheis, P. J. McMillan +13
Gaia DR3 provides radial velocities for 33 million stars and spectroscopically derived atmospheric parameters for more than five million targets. When combined with the astrometric…
The chemical signature of the Galactic spiral arms revealed by Gaia DR3
E. Poggio, A. Recio-Blanco, P. A. Palicio +8
Taking advantage of the recent Gaia Data Release 3 (DR3), we map chemical inhomogeneities in the Milky Way's disc out to a distance of 4 kpc from the Sun, using different sa…
Beyond the two-infall model I. Indications for a recent gas infall with Gaia DR3 chemical abundances
E. Spitoni, A. Recio-Blanco, P. de Laverny +7
The recent Gaia Data Release 3 (DR3) represents an unparalleled revolution in Galactic Archaeology, providing us with numerous radial velocities chemical abundances for millions of…
Solid confirmation of the broad DIB around 864.8 nm using stacked Gaia-RVS spectra
H. Zhao, M. Schultheis, T. Zwitter +26
Studies of the correlation between different diffuse interstellar bands (DIBs) are important for exploring their origins. However, the Gaia-RVS spectral window between 846 and 870…
Characterisation of Galactic carbon stars and related stars from Gaia-EDR3
Carlos Abia, Patrick de Laverny, Merce Romero +1
We extend here a previous investigation on the characteristics of Galactic carbon stars using more accurate EDR3 astrometry measurements. Based on a much larger statistics, we conf…
