Researchers have found strong evidence that Betelgeuse's unusual dimming patterns are caused by a hidden companion star, Siwarha, which creates a detectable wake as it moves through Betelgeuse's outer atmosphere, confirming long-standing hypotheses about its behavior.
Astronomers from Carnegie Mellon University have confirmed that Betelgeuse has a hidden companion star, nicknamed 'Betelbuddy,' which is a young solar-sized star. This discovery, made using NASA's Chandra X-ray Observatory and the Hubble Space Telescope, helps explain Betelgeuse's six-year brightness cycle and challenges existing models of binary star formation due to the significant mass difference between the two stars.
Astronomers have confirmed the existence of a long-suspected companion star to Betelgeuse using advanced imaging technology, explaining its six-year dimming cycle and opening new avenues for studying stellar dynamics and evolution.
Astronomers have confirmed that Betelgeuse has a tiny companion star, called BetelBuddy, which helps explain its unusual dimming patterns. Using speckle imaging with the Gemini North telescope, they identified the young star, likely born at the same time as Betelgeuse, and observed its characteristics. This discovery sheds light on Betelgeuse's variability and provides insights into its future, including its eventual engulfment by the larger star within the next 10,000 years.
Astronomers have for the first time directly observed a close stellar companion to Betelgeuse using advanced imaging techniques, solving a long-standing mystery about its periodic brightness variations and revealing that Betelgeuse may eventually cannibalize this smaller star within the next 10,000 years.
