一个隐藏的恒星在Betelgeuse轨道上运行,每2,100天就产生一次气体唤醒,解释其亮度变化。 A hidden star orbiting Betelgeuse creates a gas wake every 2,100 days, explaining its brightness changes.

使用哈勃望远镜和地基望远镜的天文学家发现了隐藏的伴星西瓦哈(Siwarha ) 、 环绕Betelgeuse(Betelgeuse ) 和每2,100天产生一次重复的气体唤醒的证据,解释红色超级巨星的长期光亮变化。 Astronomers using Hubble and ground-based telescopes have found evidence of a hidden companion star, Siwarha, orbiting Betelgeuse and creating a repeating gas wake every 2,100 days, explaining the red supergiant’s long-term brightness changes. 其伴侣在直接图像中看不见,他扭曲了贝泰尔盖斯的大气层,就像一条渡过水的船,证实了关于该恒星不正常行为的长达数十年的理论,包括其2020年暗淡。 The companion, invisible in direct images, distorts Betelgeuse’s atmosphere like a boat through water, confirming a decades-old theory about the star’s irregular behavior, including its 2020 dimming. 从近八年的数据中得出的研究结果 增进了对巨型恒星进化和二元相互作用的理解 The findings, from nearly eight years of data, advance understanding of massive star evolution and binary interactions.
