Optical Observations With Milliarcsecond Resolution Of Stars, Their Environments And Companions
Abstract
Observations with milliarcsecond resolution using the Navy Optical Interferometer have been obtained for a number of stellar systems which include high-mass binaries, eclipsing binaries, and radio stars. These observations also reveal the previously unseen companions in single-lined spectroscopic binaries via directly measured flux ratios. We will present examples of published and ongoing research efforts of these systems to illustrate how an optical interferometer contributes to our knowledge of stars, their environment, and companions. These studies include a conclusive revealing of the previously unseen companion in the single-lined binary phi Herculis, the direct determination of orbital parameters in the wide and close orbits of Algol, and revealing the orbit of beta Lyrae with spatially resolved images of the H-alpha emission.
