Orbits of Massive Binary Stars
Abstract
We are mapping the spatially resolved orbits of massive O-star binaries using the MIRCX combiner at the CHARA Array. The systems we are currently monitoring (Iota Orionis, HD 199579, and HD 193322) have angular separations ranging from 1 to 50 milli-arcseconds. Combined with spectroscopic radial velocities, we plan to measure high precision dynamical masses of the component stars. These masses will be used to test evolutionary models for massive stars.
