• Unstable binary systems may lead to “type Ia” supernovae, May 18 (Wang Ziyu) a binary star system refers to a star system in which two stars look very close and orbit around a common mass center. Binary systems are common in the Milky way, but they also include some multi star systems with three, four or even six stars. In a binary system, two stars move in elliptical orbits, and the orbital mass is relatively stable. But for three or more star systems, their trajectories are more complex. In order to accurately measure the trajectory of stars, the…
