Our sun is a lonely star. At least half the stars in our galaxy have binary companions. This was nicely illustrated in the Star Wars movie trilogy where Luke Skywalker watched two suns set on the horizon as seen from his home planet Tatooine. Now imagine three suns in the sky. This is the story for a system that once contained three co-orbiting stars.

NASA’s Hubble reveals the blue lurker star in M67, shedding light on stellar mergers and evolution

Triple star systems are more common than might be imagined – about one in ten of every Sun-like star is part of a system with two other stars. However, the dynamics of such a system are complex, and understanding the history of how they came to be even more so. Science took a step towards doing so with a recent paper by Emily Leiner from the Illinois Institute of Technology and her team. They examined a star called WOCS 14020 in the star cluster…

Colliding Stars, Stellar Siphoning, and a now a "Blue Lurker." This Star System has Seen it All

Our sun is a lonely star. At least half the stars in our galaxy have binary companions. This was nicely illustrated in the Star Wars movie trilogy where Luke Skywalker watched two suns set on the horizon as seen from his home planet Tatooine. Now imagine three suns in the sky. This is the story for a system that once contained three co-orbiting stars. Forensics with Hubble data show that the stars have had a tumultuous life. Two of the stars mer…

Hubble tracks down a 'blue lurker' among stars - Tech and Science Post

NASA’s Hubble Space Telescope has identified a rare stellar phenomenon called the “blue lurker” in the M67 star cluster. Located 2,800 light-years away, this star is part of a triple-star system and has an unusual evolutionary history. The blue lurker’s accelerated spin, taking just four days, contrasts with the typical rotation of Sun-like stars. The star’s…NASA’s Hubble Space Telescope has identified a rare stellar phenomenon called the “blue …

NASA’s Hubble Observes Rare Blue Lurker Star with Unusual Evolution in M67 Cluster

NASA has identified a rare and unusual “blue lurker” star produced during the collapse of a triple-star system in the M67 star cluster. Due to its remarkable speed, the star hides 2,800 light years away and is visible through NASA’s Hubble Space Telescope. Astronomer Dr. Emily Leiner of the Illinois Institute of Technology in Chicago led the work presented at the 245th Meeting of the American Astronomical Society in Washington, D.C. Blue Lurkers…
