Radial Velocity and Astrometric Evidence for a Close Companion to Betelgeuse

Radial Velocity and Astrometric Evidence for a Close Companion to Betelgeuse

We examine a century of radial velocity, visual magnitude, and astrometric observations of the nearest red supergiant, Betelgeuse, in order to reexamine the century-old assertion that Betelgeuse might be a spectroscopic binary. These data reveal Betelgeuse varying stochastically over years and decad...
