Abstract

We present photometric and spectroscopic observations of a faint star 4 arcsec away from the apparently normal, young early B-type star PG 0832+676, which was previously identified as being approximately 18 kpc above the Galactic plane. The differential radial velocity of the two is found to be consistent with zero within the measurement errors, suggesting physical association; however, the other available evidence implies that the companion is a low-luminosity, metal-deficient early G-type star. The implications of these data for the evolutionary status and Galactic z-distance of PG 0832+676 are discussed, and we conclude that this is a chance alignment of two unrelated objects.
