Determining the mass of the planetary candidate HD 114762 b using Gaia

Gaia data permit the unveiling of the nature of a planetary candidate. HD114762 b was the first planetary candidate to be discovered with radial velocities around a solar-like star, but the detection method did not allow us to determine its nature. Using astrometric noise provided by Gaia DR1 data, Flavien Kiefer gives a more accurate measurement of the mass of the candidate. The conclusion is that it is probably an M dwarf and not a planet.
