Description

HD 98439 was discovered to be a very close optical binary by the lunar-occultation method, for which it has repeatedly served as a prime example. It has proved to have an orbit of low eccentricity and a period of 1000 days. The inclination is about 50o. Radial-velocity traces provide no evidence of the existence of a third component that was suggested by the occultation trace. (author)
