Abstract

We present sub-milliarcseond resolution observations of two nearby rapid rotators Cephei and Ophiuchi, obtained with the CHARA array. We reconstruct an aperture synthesis image for Cep. Weal so construct gravity darkening models for both stars and precisely determine their geometry, polar and equatorial radii and temperatures,as well as their fractional rotation speed.
