Astronomers Present Strongest Evidence to Date of Betelgeuse’s Companion Star

Astronomers have released findings that represent the strongest evidence yet of a companion to Betelgeuse. The study combines data from multiple telescopes and observational techniques. Researchers detected signals consistent with a secondary object orbiting the red supergiant. Analysis suggests the companion may influence Betelgeuse’s variability and mass loss. The results refine models of the star’s future evolution and potential supernova. The team plans follow‑up observations to confirm the companion’s properties. The discovery has sparked discussion about binary interactions in massive stars. The paper is reported on Phys.org and adds a new dimension to Betelgeuse research.
