High Velocity Spectroscopic Binary Orbits from Photoelectric Radial   Velocities: BD +82 565A
  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 ~830 AU. The system's barycenter velocity V_0 = -86.7 km/s, the transverse velocity V_t = 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.
