Radial velocities of population II binary stars. I.
Radial velocities for 114 Hipparcos stars, mostly high transversevelocity binaries without previous radial velocity measurements, arepublished. Measurements are made with the CORAVEL-type radial velocityspectrometer. The accuracy of measurements is better than 1 km/s. Twostars, BD +30 deg 2129A and HD 117466AB are found to be radial velocityvariables, and three more stars, HD 119515A, HD 131597AB, and HD 153344,are possible radial velocity variables.

Common proper motion stars in the AGK 3
A search was made of common-proper-motion (CPM) systems among AGK 3stars. The selection of physical systems was based upon the ratiobetween the angular separation (rho) and the proper motion (mu); the CPMstars found are presented in two tables. Table I lists systems withrho/mu less than 1000 years. It contains 326 entries, and the proportionof optical pairs is estimated to be 1 percent. Table II lists systemswith rho/mu in the range 1000 to 3500 years; it contains 113 systems,but only 60 percent of them are physical. Nevertheless, these systemsoften have separations larger than 10,000 AU and are the mostinteresting for the study of the tail of the distribution function ofthe semimajor axes.
