THE SPECTROSCOPIC-SPECKLE TRIPLE SYSTEM HR-6469

HR 6469 consists of an evolved G star and a close pair of stars, belie ved to be on the main sequence, the righter of which is an early F sta r. Shallow eclipses have been detected in the close pair [Boyd et al. IBVS, 675 (1985)], and the components of the wide system have been res olved over most of the orbit by speckle interferometry [McAlister & Ha rtkopf, Second Catalog of Interferometric Observations of Binary Stars , Center for High Angular Resolution Astronomy, Contribution No. 2 (CH ARA), 1988]. This paper presents radial velocities, obtained at the Da vid Dunlap, McDonald, Kitt Peak and Dominion Astrophysical observatori es, for the G star and the primary of the close pair, along with solut ions for elements of both the long- and short-period orbits, from thos e radial velocities and the speckle data, some of which have not previ ously been published. New spectrophotometry permits revisions of both the evolved star's spectral classification and the rotational velocity of the primary of the close pair, but not detection of the spectrum t he third component. These results, in combination with those from the light-curve solution of Van Hamme et al. [AJ, 107, xxx (1994)], enable us to determine the masses, radii, and luminosities of all three tars , and to discuss the evolutionary state of the system.
