Radial velocity follow-up of PLATO transiting candidates

PLATO is a proposed ESA mission devoted to better understand the properties of exoplanetary systems. As such it will detect and characterise exoplanets using their transit signature in front of a large sample of bright stars and simultaneously measuring the seismic oscillations of the parent star of these exoplanets. An intensive effort of ground-based observations are required to complement the observations made by PLATO to allow for further exoplanetary characterization. Here we present some elements about the strategy and organization of the ground-based radial velocity follow-up of PLATO transiting candidates to establish the nature of the transit events and to characterize their masses from earth-like planets to brown-dwarfs.
