Spectroscopic binary orbits from photoelectric radial velocities - Paper 149: 46 Bootis

46 Bootis has long been suspected of being a spectroscopic binary on the ba sis of evidence now found to be mistaken. We show that it has an orbital pe riod very close ro seven years and a very high eccentricity (0.83). The mas s function, together with the non-detection of the secondary star, suggests that the latter is a G or K dwarf.
