Title The second Gaia data release : content and first scientific results
Abstract The second Gaia data release (DR2) has been published on 25 April 2018. It contains the parallaxes and proper motions of 1.3 billion sources (versus 2 millions in DR1) as well as the positions and G-magnitudes of 400 millions additional sources. DR2 also contains new products, including Bp/Rp-magnitudes of 1.4 billion sources, 7.2 millions line-of-sight velocities, stellar parameters for several tens millions stars, the detection of half a million variable stars and 14000 asteroids. In this seminar, I will detail the contents and performances of the release, discuss the usage of the data and I will present some of the first scientific results.
