We are obtaining high‐resolution, red‐wavelength spectra at McDonald and Kitt Peak National Observatory to improve the orbits of known spectroscopic binaries that are potential targets for ground‐based optical interferometers. The combination of such observations will produce three‐dimensional orbits from which very accurate masses and orbital parallaxes can be obtained for double‐lined systems. This spectroscopic program will be expanded and placed on the menu of the 2 meter Automatic Spectroscopic Telescope of Tennessee State University once it commences routine operation.
