The cosmic bodies’ wobbles were measured based on alterations in light they give off, which is also referred to as the Doppler effect.
Researchers have spotted the fastest brown dwarf stars ever known in the universe, spinning at such a breakneck speed that they could rip themselves to pieces.
“We seem to have come across a speed limit on the rotation of brown dwarfs,” said Megan Tannock, the Western University physics and astronomy graduate student who led a new study, the findings of which will be published in an upcoming issue of ....

Extreme Brown Dwarfs Found Spinning at Their Physical Limits

New research documents the fastest-spinning brown dwarfs on record. 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.

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). ....

Astronomers have found the fastest brown dwarf stars in the known universe, spinning at such a rapid rate that they risk ripping themselves asunder.
A brown dwarf, otherwise known as a ‘failed star’, are formed when stars cannot gather enough mass to trigger nuclear reactions, which would convert their cores from hydrogen into helium.
“We seem to have come across a speed limit on the rotation of brown dwarfs,” said Megan Tannock, the Western University physics and astronomy graduate student who led the discovery. ....

Astronomers at Western University have discovered the most rapidly rotating brown dwarfs known. They found three brown dwarfs that each complete a full rotation roughly once every hour. That rate is so extreme that if these failed stars rotated any faster, they could come close to tearing themselves apart. Identified by NASA s Spitzer Space Telescope, the brown dwarfs were then studied by ground-based telescopes including Gemini North, which confirmed their surprisingly speedy rotation. ....
