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
- B. Famaey, A. Jorissen, C. Turon

- PhysicsAstronomy & Astrophysics
- 25 April 2018
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
- Gaia Collaboration, C. Babusiaux, T. Zwitter
- PhysicsAstronomy & Astrophysics
- 25 April 2018
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
- L. Ruiz-Dern, C. Babusiaux, Frédéric Arenou, C. Turon, R. Lallement
- Physics
- 16 October 2017
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…

The Hyades: distance, structure, dynamics, and age
- M. Perryman, A. Brown, F.Crifo
- Physics
- 23 July 1997
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…
