Scientific paper

Spectroscopic orbits have been computed for the double-lined binaries Gliese 148 and GJ 1237 = HD 183255, the latter being a good candidate for resolution by speckle interferometry. Single-lined orbits are given for Gliese 688 = HD 160346 and Gliese 586 A = HD 137763. Gl 586 A has an eccentricity of 0.976 and should be observed during next periastron passage in 1992.6. The radial velocity of its companion Gl 586 B can also be variable.
