(multiple star system demonstrating affects of mass transfer)
(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.
