Scientific paper

Radial velocities determined with the photoelectric spectrometers at Palomar and Cambridge Observatories are used to derive the orbits of four spectroscopic binaries which have been considered to be members of the Hyades. 23°635, vB 162, and vB 182 have γ velocities strongly supporting their membership in the cluster; J 318 is shown to be a nonmember but to be a companion of the brighter star HD 29836 about 2' distant in the sky. vB 162 is conspicuously double lined, with spectral types of G4V and G7V being estimated for the components; indirect evidence suggests that the secondary star in 23°635 has also been detected, and that the system consists of K3V and K8V components.
