True masses using radial velocity data with HIPPARCOS and Gaia astrometry

Astronomy & Astrophysics
Context. Long-period companions are detected and characterised thanks to long-baseline radial velocity surveys. By combining Doppler time series with astrometry, and in particular with the proper motion anomalies technique, it is possible to put strong ...
