We present the first resolved image of a star observed with a separated-element optical aperture synthesis telescope. Observations of the M2 lab supergiant Betelgeuse (a Orionis) were made at 830 nm with the Cambridge Optical Aperture Synthesis Telescope (COAST) during 1995 October. Unusually, the source intensity distribution was highly symmetric at the time of observation we find no evidence for the brightness asymmetries observed in earlier studies. Our data indicate a strongly limb-darkened… Expand
