Scientific paper

The transit method used by the Eddington space mission to find extra-solar planets allows us to characterize the size of a planet but not its mass. Ground-based Doppler measurements can then avoid confusion between planets and white or brown dwarfs by providing the actual companion mass. We review here the radial-velocity accuracy to be expected for the determination of the planetary masses of transit candidates detected by Eddington. The future HARPS spectrograph (High Accuracy Radial velocity Planetary Search), to be installed on the 3.6-m ESO telescope (La Silla, Chile) at the end of 2002, will be able to characterize the mass of a large number of these detected planets.
