Abstract [eng] The spectroscopic orbit of a circumpolar high proper motion visual binary BD +82 565 A component is determined from 57 CORAVEL radial velocity measurements. A short period P = 12.69 d and a moderate eccentricity e = 0.30 are obtained. The visual system AB has a projected spatial separation of about 830 AU. The system's barycenter velocity V0 = --86.7 km/s, the transverse velocity Vt = 118.7 km/s and the Galactic spatial velocity components U = --62.6 km/s, V = --84.1 km/s and W = --84.2 km/s give evidence that it belongs to the thick disk of the Galaxy.
