There is a class of stars called Eclipsing Binary stars, where a star can go in front of another star periodically and block out a portion of its light. The most famous of these is Algol in Perseus.
Recently a Triple eclipsing binary has been discovered, TIC 29574134. Two close together sun-like stars are orbited by a red giant star such that, when the red giant star goes behind the sunlike stars, the sunlike stars block some of the red giant's light, in steps.
