GG Tauri
GG Tauri, often abbreviated as GG Tau, is a quintuple star star system, system in the constellation Taurus (constellation), Taurus. At a distance of about 450 light years (140 parsecs) away, it is located within the Taurus-Auriga Star Forming Region. The system comprises three stars orbiting each other in a hierarchical triple system, known as GG Tauri A, and another binary star system more distant from the central system, known as GG Tauri B. The system is unusual because it contains two distinct circumstellar disks: one surrounding the entirety of GG Tauri A, and another surrounding the brightest star of GG Tauri A. Its large size and close distance make it ideal to study how exoplanets form within multiple star systems. Properties GG Tauri consists of five stars, which are T Tauri stars – a class of variable stars that show irregular changes in brightness. These stars are extremely young and more luminous than their main sequence counterparts, because they have not ...
