Quadruple Star System
Recent research has revealed a unique quadruple star system in our galaxy. Named UPM J1040−3551 AabBab, it consists of two cold brown dwarfs orbiting a pair of young red dwarf stars. This rare configuration has never been observed before. The finding promises new vital information about the nature of brown dwarfs and star formation. What Is the Quadruple Star System? The system contains four celestial bodies grouped in two pairs. One pair is young red dwarf stars, common and relatively bright. The other pair consists of cold brown dwarfs, faint objects about the size of Jupiter. The brown dwarfs orbit the red dwarfs in a hierarchical arrangement. This system is unique because brown dwarfs rarely have companions and are seldom found in multiple-star systems. Characteristics of Brown Dwarfs Brown dwarfs are objects that form like stars from gas clouds but lack the mass needed to sustain hydrogen fusion. This makes them “failed stars.” They share traits with gas giant planets, such...
