The Be star Alpha Arae (artist's impression)
Artist's impression of the Be star Alpha Arae. The star is rotating with a velocity close to its break-up velocity and loses mass through a stellar wind emerging predominantly from the poles and reaching velocities of the order of 2000 km/s. The star is surrounded by a disc in Keplerian rotation.
