Researchers Find that Bright Nearby Double Star Fomalhaut Is Actually a Triple

The nearby star system Fomalhaut - of special interest for its unusual exoplanet and dusty debris disk - has been discovered to be not just a double star, as astronomers had thought, but one of the widest triple stars known.

In a paper recently accepted for publication in the Astronomical Journal and posted today to the preprint server arXiv, researchers show that a previously known smaller star in its vicinity is also part of the Fomalhaut system.
