(Beta Per, β Per, Beta Persei, β Persei)
(multiple star system demonstrating effects of mass transfer)

Algol (Beta Persei, β Persei, Beta Per, or β Per) is a triple star system including an eclipsing binary, and whose stars do not appear to match normal main-sequence evolution, a consequence of mass transfer between stars. Characteristics (β Per Aa1):

The "wrong" characteristics of the stars due to the accretion between stars is known as the Algol paradox.


The terms Algol variable (or just Algol) is a class of variable stars for which Algol is the prototype.
