Results from Gaia's planet detection tests
15 September 2003Members of the Planetary Systems Working Group have reported the first results of their tests of Gaia's exoplanet detection capabilities, using simulated data matching the results expected from the real mission.
In a detailed `double blind test', data simulated by Torino Observatory astronomers Mario Lattanzi and colleagues was processed independently by Alessandro Sozzetti (Pittsburgh/CfA), and Dimitri Pourbaix and Sylvie Jancart (Bruxelles). The detection and orbit fitting solutions are in line with the formal predictions, and underline Gaia's capability of detecting many thousands of exoplanets from their astrometric wobble.
