Extreme Brown Dwarfs Found Spinning at Their Physical Limits

The objects are rotating so rapidly that, should they rotate any faster, they’d likely tear themselves apart. The finding could mean that these so-called “failed stars” have a built-in speed limit. Advertisement The three brown dwarfs are spinning 10 times faster than Jupiter, completing a single rotation around their axes once every hour. That’s about 30% faster than the fastest spinning brown dwarfs on record, according to the new paper, which is set to appear in an upcoming issue of the Astronomical Journal (a preprint is currently available at the arXiv).
