Observations of Ara Be stars -> Hot main sequence stars with : • Emission in H • Circumstellar shell • Rotation • Non radial pulsations • Flares : Mass Ejection ? S. Lacour & X. Haubois
UV plane and visibilities • Without calibration With calibration
But the information is in the phase! (differential) • 0.3 rad rms 16 degree rms : The closure phase measurements are very noisy • The differential phase is great!
