The Spectroscopic-Speckle Triple System HR 5472

DAO coude radial velocities obtained between 1975 and 1990 have been used to revise Harper and Blanchet's (1937) spectroscopic orbital elements of the single-line triple system HR 5472. A visual orbit for the long-period pair, derived from the data presented by McAlister and Hartkopf (1988) and by McAlister et al. (1990), is in good agreement with the spectroscopic one, and a solution has been obtained which fits the speckle and spectroscopic data simultaneously. Even though only the primary star's spectrum has been observed, that solution makes it possible to put some limits on the masses of the components of HR 5472.
