It was unresolved by prior speckle interferometry observations (McAlister et al. 1989, 1993). We detected a candidate companion, but with a separation of over an arcsecond. That is too far to be the astrometric companion and thus is likely a third component. The adaptive optics system at the 3.6 m Advanced Electro-Optical System telescope was used to measure the astrometry and differential magnitude in I band of binary star systems between 2002 and 2006. We report 413 astrometric and photometric measurements of 373 stellar pairs.

An astrometric binary is a binary star in which the presence of a dim component is revealed by a regular "wobble" or oscillation in the motion of a much brighter component. Not many binaries have been detected astrometrically mainly because observations must be made regularly over a long period of time to detect the periodic wobbles in the motion of the brighter or primary component.

We ﬁnd that the photocentric orbit has a period P = 633.0 1.7 days, somewhat longer than previous results, eccentricity of e = 0.42 0.03, and we estimate that the semimajor axis of the orbit of the primary is a 1 »0.32 AU, consistent with previous results. The Low-Mass Astrometric Binary LSR1610 0040 Seth C. Koren 1;3, Cullen H. Blake , Conard C. Dahn2, and Hugh C. Harris2 ABSTRACT Even though it was discovered more than a decade ago, LSR1610 0040 re-mains an enigma. This object has a peculiar spectrum that exhibits some fea-tures typically found in L subdwarfs, and others common in the spectra Astrometry is the oldest search method for extrasolar planets and originally popular because of its success in characterizing astrometric binary star systems.

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.’. A visual binary is a binary system in which the component stars of the system can be individually resolved through a telescope.

Terms and Conditions; Get Published Some astrometric binaries have subsequently been resolved by speckle interferometry. Components calculated to have extremely low mass may be either faint red dwarfs, brown dwarfs, or possibly even planets.astrometric binary: The presence of an unseen companion causes a visible star to wobble from side to side as it moves through space. Astrometric Binary. If only one star is visible, but we can detect that it wobbles about an unseen centre-of-mass, then we have an astrometric binary.
