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 1 Summary of the astrometric, photometric, and survey properties

Anthony G. A. Brown, +590 more
TL;DR: The first Gaia data release, Gaia DR1 as discussed by the authors, consists of three components: a primary astrometric data set which contains the positions, parallaxes, and mean proper motions for about 2 million of the brightest stars in common with the Hipparcos and Tycho-2 catalogues.
Journal ArticleDOI

The Tycho Double Star Catalogue

TL;DR: The Tycho Double Star Catalogue (TDSC) as mentioned in this paper is a catalogue of absolute astrometry and B T, V T photometry for 66219 components of 32631 double and multiple star systems.
Journal ArticleDOI

Statistical constraints for astrometric binaries with nonlinear motion

TL;DR: In this article, the authors derived useful constraints on the orbits and mass ratios of astrometric binaries in the Hipparcos catalog from the measured proper motion differences of Hipparcians and Tycho-2 (??), accelerations of proper motions, and second derivatives of proper motion.
