Abstract

An optical interferometer with long baselines and high spectral resolution could be used to determine the rotation rate of a star and the orientation of its rotation axis. Orientation is information that has previously been determined only statistically for single stars. Knowing the orientation would allow solution of currently intractable problems in star formation and stellar evolution.
