Journal ArticleDOI

Gaia Data Release 1 - Astrometry: one billion positions, two million proper motions and parallaxes

Lennart Lindegren, +83 more
TL;DR: Gaia Data Release 1 (Gaia DR1) as discussed by the authors contains a large amount of data collected by the Gaia satellite during the first 14 months of its operational phase, including positions, parallaxes, and proper motions to Hipparcos-type precision or better.
Journal ArticleDOI

Gaia Data Release 2 - Observational Hertzsprung-Russell diagrams

C. Babusiaux, +451 more
TL;DR: Gaia Data Release 2 provides high-precision astrometry and three-band photometry for about 1.3 billion sources over the full sky as mentioned in this paper, which is unprecedented in both precision and coverage of the various Milky Way stellar populations and stellar evolutionary phases.
Journal ArticleDOI

Gaia Data Release 2. Observations of solar system objects

Federica Spoto, +501 more
TL;DR: In this paper, the authors describe the processing of the Gaia DR2 data, and describe the criteria used to select the sample published in Gaia DR 2, and explore the data set to assess its quality.
Journal ArticleDOI

Gaia Data Release 2. Kinematics of globular clusters and dwarf galaxies around the Milky Way

Amina Helmi, +484 more
TL;DR: In this paper, the second data release of the Gaia mission and its power for constraining many different aspects of the dynamics of the satellites of the Milky Way is demonstrated. But the accuracy of the errors, statistical and systematic, are relatively well understood.
Journal ArticleDOI

Gaia Early Data Release 3. The astrometric solution

Lennart Lindegren, +104 more
TL;DR: Gaia Early Data Release 3 (Gaia EDR3) as mentioned in this paper contains results for 1.812 billion sources in the magnitude range G = 3-21 based on observations collected by the European Space Agency Gaia satellite during the first 34 months of its operational phase.
