Astronomers have reported new evidence suggesting that a previously hidden companion star is interacting with the atmosphere of Betelgeuse, the prominent red supergiant in the constellation Orion. According to the findings, the smaller star, referred to as Siwarha, may be plowing through Betelgeuse’s enormous outer envelope, generating disturbances that subtly stretch and distort the supergiant’s shape. The conclusions are based on recent radio observations that offer a clearer view of the dynamic environment surrounding the aging star.
The research adds to a growing body of work examining how stellar companions influence the evolution of massive stars. Betelgeuse has drawn sustained scientific and public attention in recent years following episodes of unexplained dimming, and the proposed interaction with Siwarha could help explain some of its irregular behavior. The team cautions that further observations will be needed to confirm the companion’s role and to determine how its passage affects the supergiant’s atmosphere over time. The findings have been presented in the context of ongoing radio monitoring campaigns.
