Abstract

Detection of two close optical companions to the red supergiant α Ori was accomplished in 1983 November on the Steward Observatory 2.25 m telescope. A new two-dimensional photon counting camera was used for data recording, and speckle imaging was used for image reconstruction. The closer of the two sources is located at 0arcsec.06±0arcsec.01 from α Ori (P.A. = 273°), the more distant at 0arcsec.51±0arcsec.01 (P.A. = 278°). An analysis of these results and of earlier polarization data favors an interpretation in which the two optical sources are stellar companions to α Ori.
