A review of 70 years with astrometry
In 1953 I heard of an experiment in 1925 by Bengt Str\"omgren where he observed transit times with the meridian circle at the Copenhagen University Observatory measuring the current in a photocell behind slits when a star was crossing.

True masses using radial velocity data with HIPPARCOS and Gaia astrometry
Astronomy & AstrophysicsContext. 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 ...
