"Betelgeuse's Baffling Behavior: A Giant Star Defying Astrophysics"
TL;DR
New research suggests that Betelgeuse's apparent fast rotation may be an illusion caused by its turbulent, convective surface rather than actual rapid rotation. Observations from the ALMA telescope, which previously indicated high rotation speeds, may actually be detecting the effects of the star's violent convection. Further high-resolution observations are needed to clarify Betelgeuse's true rotation speed, which could provide insights into its evolution and behavior as a red supergiant star.
