Abstract:Context. Although more than one thousand substellar companions have already been detected with the radial velocity (RV) method, many new companions remain to be detected in the public RV archives.
Aims. We wish to use the archival data obtained with the ESO/HARPS spectrograph to search for substellar companions.
Methods. We used the astronomic acceleration measurements of stars obtained with the HIPPARCOS and Gaia satellites to identify anomalies that could be explained by the presence of a companion. Once hin… Show more
