D 13.5 at 77", optical. Speckle interferometric observations in 1983 November (Karovska et al. 1986, ApJ, 308, 360) show A to be a triple system with closer companion at 0.06" (mag. diff. 3.4 at H alpha) and more distant companion at 0.51" (mag. diff. 4.6 at H alpha). Miscellaneous Radio star. Circumstellar shell of gas and dust. The gas shell detached from photosphere at about 5 stellar radii. Diam of optically thin dust shell possibly 1".5. Surrounded by reflection nebula. Gas shell up to 100 R, dust shell from 12 to 250 R. Highly limb darkened. Name BETELGEUSE; Betelguex; Betelgeuze; Beteiguex; Al Mankib. Radius or Diameter The first star whose diameter was measured with the interferometer, .047", by Michelson and Pease at Mt. Wilson in 1920. Radial and/or Rotational Velocity Expanding circumstellar shell, extending at least 29" or about 600 stellar radii. If rate constant, initial potassium ejection about 2700 years ago. 2.85-cm radio emission indicates mass loss. Spectrum Ultraviolet FeII emission. 5-micron observations indicate carbon monoxide. STRATOSCOPE II observations indicate infrared H2O bands. UV observations from OAO-2 indicate C and O underabundant. MgII emissions indicate a cooler shell surrounding the supergiant.
