the brightest star in the constellation. It is a short-period variable star and a binary whose components have a mutual orbital period of 4.15 years, but this can only be discerned by spectroscopic methods. The variation in its brightness over a period of 5.09 days is only 0.1mag and therefore not perceptible to the naked eye. The star belongs to the type of stars α2 Canum Venaticorum, which also show magnetic field fluctuations. |
