Similarly, a known binary star may prove to be an astrometric multiple star.

noun. A binary star system in which one companion is invisible, but is known to be present from its effect on measurements relating to the other. ‘As technology has improved over time, a number of binaries originally identified as astrometric binaries have been upgraded to visual binary because of the sighting of the secondary in the system.’. ‘In astrometric binaries we see one star's position wobble periodically in response to the gravity of its unseen companion.’ ‘During the period 1950 to 1970, a number of stars, most notably Barnard's star, were claimed to be astrometric binaries with substellar companions.’ 2019-09-27 · HD 34540 is a southern, seventh-magnitude G-type star at a distance of 35 pc.
