GG Tau

(GG Tauri)
(much-studied quadruple star system)

GG Tau (or GG Tauri) is a star system combining a number of characteristics that make it useful for study. It is a quadruple system made up of two binary stars, and for being binaries, more accurate mass estimates can be made than otherwise. It includes a T-Tauri star, and the entire system is surrounded by a massive circumstellar disk. Being close enough for good observation, it is an interesting lab for planet formation theories and study. Characteristic (GG Tau Aa):
