Binary Star Orbits from Speckle Interferometry. XI. Orbits of Twelve Lunar Occultation Systems.
Abstract
Stars detected as double by lunar occultation are logical targets for speckle interferometric and spectroscopic investigations. This paper presents twelve orbits for interferometric systems; eight of these had no previous orbits and the other four have new orbit determinations which represent improvements on previously published elements. Where trigonometric parallaxes are not available, spectroscopic parallaxes are calculated, and model-dependent masses are determined for ten components whose results seem most reasonable.
