Caught speeding: Clocking fastest-spinning brown dwarfs

Gemini North observations help identify rotational speed limit for brown dwarfs
Three brown dwarfs, often called “failed stars,” are spinning faster than any others.
Astronomers have discovered the most rapidly rotating brown dwarfs three brown dwarfs that each complete a full rotation roughly once every hour. The rate is so extreme that if they rotated any faster, they could come close to tearing apart.
Brown dwarfs are, simply put, failed stars. They form like stars but are less massive and more like giant planets.
Astronomers first measured the rotation speeds of these brown dwarfs using the Spitzer Space Telescope and confirmed them with follow-up observations with the Gemini North telescope on Maunakea in Hawaii and the Magellan Baade telescope in Chile. Gemini North is one of the pair of telescopes that make up the international Gemini Observatory, a program of NSF’s NOIRLab. ....

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 ....
