They are produced when a binary star system - two stars gravitationally bound to each other - ventures too close to a supermassive black hole. "The intense gravitational forces tear the pair apart.

If this were to be true, they would be part of the fastest-moving stars in the galaxy, all by using gravity for energy. Reasons for moving may be due to needing to escape an impending supernova ...

A study based on the trajectory of nine fast-moving stars observed at the fringes of the Milky Way provides strong evidence for the existence of a supermassive black hole inside the Large ...
