The Gaia mission

T. Prusti, +624 more
TL;DR: Gaia as discussed by the authors is a cornerstone mission in the science programme of the European Space Agency (ESA). The spacecraft construction was approved in 2006, following a study in which the original interferometric concept was changed to a direct-imaging approach.
Journal ArticleDOI

Gaia Data Release 2 - First stellar parameters from Apsis

TL;DR: The second Gaia data release (Gaia DR2) contains, beyond the astrometry, three-band photometry for 1.38 billion sources as discussed by the authors, which is used to infer stellar effective temperatures, T eff, for all sources brighter than G = 17 mag with T eff in the range 3000-10 000 K (some 161 million sources).
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

The Gaia astrophysical parameters inference system (Apsis) - Pre-launch description

TL;DR: In this article, the authors describe the data analysis system put together by the Gaia consortium to classify these objects and to infer their astrophysical properties using the satellite's data, covering single stars, (unresolved) binary stars, quasars, and galaxies, all covering a wide parameter space.
