An image reconstruction of alpha Orionis.
Abstract
A description is given of an attempt to reconstruct an image of the star Alpha Orionis from a map of fringe visibilities obtained on November 30, 1980 with the CFH Telescope in Hawaii. The maximum entropy algorithm proposed by Gull and Daniell (1978) was used. The data were obtained through a 90 A bandwidth filter centered at 5350 A - a window chosen because it avoids strong molecular absorption bands in the stellar spectrum. The interferometric image reconstruction indicates that dust condensation may well occur close to the stellar disk.
