Preliminary Orbital Elements of Four Interferometric Binary Stars

摘要

We present preliminary orbital elements for the four interferometric binary star systems WDS 01017+2518, 02262+3428, 02442-2530, and 11268-5310. For all stars these are the first orbits that have been published. The data are accompanied by uncertainty estimates, residuals, and ephemerides, as well as dynamical parallaxes and individual star masses. In all four cases regular observations within the coming years are encouraged to test the orbital solutions.
