(multiple star system demonstrating affects 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. It is also the prototype for a class of variable stars called Algol variables, or just Algols.
