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: Observational Hertzsprung-Russell diagrams

C. Babusiaux, +451 more
TL;DR: In this article, the power of the Gaia DR2 in studying many fine structures of the Hertzsprung-Russell diagram (HRD) was highlighted, depending in particular on stellar population selections.
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 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).
