Beta Lyrae Aa is a [[semidetached binary]] system made up of a [[stellar class]] B6-8 primary star and a secondary that is probably also a B-type star. The fainter, less massive star in the system was once the more massive member of the pair, which caused it to evolve away from the [[main sequence]] first and become a [[giant star]]. Because the pair are in a close orbit, as this star expanded into a giant it filled its [[Roche lobe]] and transferred most of its mass over to its companion.
