概要
New radio observations reveal that Betelgeuse’s atmosphere has largely recovered from its mysterious 2019 dimming. But astronomers have uncovered another intriguing clue: a companion star called Siwarha, whose orbit appears to create a distinctive wake inside the supergiant’s atmosphere. Further observations could reveal how this hidden stellar interaction works and offer new insights into the final stages of massive stars.
