Scientific paper

Fifteen stars are analyzed for rho, mu and perturbations over an average time interval of 38 yr on plates taken with the Sproul 61 cm refractor. All of the stars are closer than 20 pcs except one, and range from third to sixth apparent magnitude. The spectral types range from F6 to K2. Unseen companions were discovered for two stars and the photocentric orbits are well established; several others are likely candidates.
