Ultracool dwarfs in Gaia DR3

L. M. Sarro, A. Berihuete, R. L. Smart +36

Aims. In this work we use the Gaia DR3 set of ultracool dwarf candidates and complement the Gaia spectrophotometry with additional photometry in order to characterise its global pr…

Spiral-like features in the disc revealed by Gaia DR3 radial actions

P. A. Palicio, A. Recio-Blanco, E. Poggio +3

We aim to explore the actions of the new Gaia DR3 astrometry to find structures in the Galactic disc. We compute the actions and the orbital parameters of the Gaia DR3 stars with f…

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…

Gaia Data Release 3: Analysis of the Gaia BP/RP spectra using the General Stellar Parameterizer from Photometry

R. Andrae, M. Fouesneau, R. Sordo +80

We present the General Stellar Parameterizer from Photometry (GSP-Phot), which is part of the astrophysical parameters inference system (Apsis). GSP-Phot is designed to produce a h…

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…
