Gaia Data Release 2
Context. For Gaia DR2, 280 million spectra collected by the Radial Velocity Spectrometer instrument on board Gaia were processed, and median radial velocities were derived for 9.8 million sources…

Local kinematics of K and M giants from CORAVEL/Hipparcos/Tycho-2 data: Revisiting the concept of superclusters
The availability of the Hipparcos Catalogue has triggered many kinematic and dynamical studies of the solar neighbourhood. Nevertheless, those studies generally lacked the third component of the…

The Three-Dimensional Universe with Gaia
Gaia Data Release 2
Context. The Gaia Data Release 2 (DR2) contains more than half a million sources that are identified as variable stars. Aims. We summarise the processing and results of the identification of variable…

Gaia Data Release 2
Context. Gaia Data Release 2 provides high-precision astrometry and three-band photometry for about 1.3 billion sources over the full sky. The precision, accuracy, and homogeneity of both astrometry…

Empirical photometric calibration of the Gaia Red Clump: colours, effective temperature and absolute magnitude
Gaia Data Release 1 allows to recalibrate standard candles such as the Red Clump stars. To use those, they first need to be accurately characterised. In particular, colours are needed to derive the…

Gaia Data Release 2
Context. The ESA Gaia mission provides a unique time-domain survey for more than 1.6 billion sources with G ≲ 21 mag. Aims. We showcase stellar variability in the Galactic colour-absolute magnitude…

Gaia Data Release 3. Catalogue validation
TLDR
Property of coverage, accuracy and precision of the data are provided by the numerous tests presented here and jointly analysed to assess the data release content, which confirms the quality of the published data, Gaia DR1 being the most precise all-sky astrometric and photometric catalogue to-date.

The Hyades: distance, structure, dynamics, and age
We use absolute trigonometric parallaxes from the Hipparcos Catalogue to determine individual distances to members of the Hyades cluster, from which the 3-dimensional structure of the cluster can be…
