Possible Discovery of Dark Matter Star in Strange Star System

Astronomers have discovered a peculiar star system observed by the European Space Agency's Gaia satellite, which may be a never-before-seen type of star made of invisible dark matter. The system consists of a sunlike star and a mysterious companion, which is much more massive. While the companion could be a black hole, researchers suggest it could be a clump of dark matter particles, known as boson stars. The researchers pointed out that a simple model of boson dark matter could produce enough boson stars to make this result in the Gaia data plausible, and that replacing a putative black hole with a boson star could explain all of the observational data.
