Gaia and the search for other planets: combining astrometry and radial velocity

L. Benamati

Abstract.
Extensive radial-velocity follow-up campaigns of planetary systems detected by Gaia will be particularly valuable to a) search for undetected lowmass planets, b) help to characterize short-period companions, c) deepen our understanding of the orbital architectures of planets orbiting distant young stars, d) improve the phase coverage for planets on orbital periods longer than the timeline of the Gaia measurements, and e) refine the characterization of multiple-planet systems where the number of free fitting parameters will be similar to the number of Gaia measurements. The main focus of my project is on the development of tools to carry out simultaneous radial-velocity and astrometric orbital fits because it will allow us to derive more precise parameters.
