Mu¹ Scorpii
Mu1 Scorpii (μ1 Scorpii, abbreviated Mu1 Sco, μ1 Sco) is a binary star system in the southern zodiac constellation of Scorpius. The combined apparent visual magnitude of the pair is about magnitude 3, making it one of the brighter members of Scorpius. Based upon parallax measurements, the distance of this system from the Sun is roughly 500 light-years (150 parsecs). This system is a member of the Scorpius–Centaurus association, the nearest OB association of co-moving stars to the Sun. The primary (Mu1 Scorpii Aa) is formally named Xamidimura , from the Khoekhoe 'the (two) eyes of the lion'. Properties Mu1 Scorpii is an eclipsing binary of the Beta Lyrae type. Discovered to be a spectroscopic binary by Solon Irving Bailey in 1896, it was only the third such eclipsing pair to be discovered. This is a semidetached binary system where the secondary is close to filling its Roche lobe, or it may even be overflowing. The two stars revolve each other al ...
