Gaia Early Data Release 3: The astrometric solution

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

Gaia Data Release 3. Summary of the content and survey properties

Gaia Collaboration A. Vallenari, +454 more
TL;DR: The third data release of the European Space Agency's Gaia mission, GDR3 as discussed by the authors , contains the same source list, celestial positions, proper motions, parallaxes, and broad band photometry in the G, G$BP}$, and G$RP}$ pass-bands already present in the Early Third Data Release.
Journal ArticleDOI

Gaia Data Release 1. Open cluster astrometry: performance, limitations, and future prospects

F. van Leeuwen, +592 more
TL;DR: The first Gaia Data Release contains the Tycho-Gaia Astrometric Solution (TGAS) component by means of the astrometric data for open clusters as discussed by the authors, which is a subset of about 2 million stars for which, besides the position and photometry, the proper motion and parallax are calculated using Hipparcos and Tycho 2 positions in 1991.
Journal ArticleDOI

Gaia Early Data Release 3 - The Gaia Catalogue of Nearby Stars

R. L. Smart, +458 more
TL;DR: In this paper, a clean and well-characterised catalogue of objects within 100 pc of the Sun from the Gaia Early Data Release 3 is presented, which contains at least 92% of stars of stellar type M9 within 100pc of the sun.
Journal ArticleDOI

Gaia Data Release 2: The astrometric solution

Lennart Lindegren, +92 more
TL;DR: Gaia Data Release 2 (Gaia DR2) contains results for 1693 million sources in the magnitude range 3 to 21 based on observations collected by the European Space Agency Gaia satellite during the first 22 months of its operational phase as mentioned in this paper.
