Fastest rotating star found

Astronomers have found the the fastest rotating star to date. The massive, bright young star called VFTS 102 is located in the Large Magellanic Cloud, and rotates 100x faster than our sun does. Centrifugal forces from this dizzying spin rate have flattened the star into an oblate shape and spun off a disk of hot plasma, seen edge on in this view from a hypothetical planet. The star may have "spun up" by accreting material from a binary companion star. The rapidly evolving companion later exploded as a supernova. Source: NASA |
