Save This Word!

A variable star whose change in luminosity is caused by two or more stars in a binary or multiple system eclipsing each other rather than by any intrinsic property of the star itself. The period of variation coincides with the orbital period of the system and can range from a few minutes to several years. See more under binary star multiple star.
