【中国新闻网】人类首次!中国天关卫星或捕捉到中等质量黑洞“进食”白矮星
Zhong Guo Xin Wen Wang· 2026-02-11 01:53
这是人类首次捕捉到如此极端的黑洞"进食"现场场景,并实现"拍照"取得直接证据,从而刷新了人 类对极端天体物理过程的认知。 天文学领域这项突破性的黑洞研究新进展,由中国科学院国家天文台联合郑州大学、香港大学等40 余家高校和科研院所的合作者共同完成,相关论文近日以封面文章形式在最新一期国际学术期刊《科学 通报》(Science Bulletin)发表。 天关卫星科学团队称,此次发现的核心,在于天关卫星搭载有独特而互补的两台X射线望远镜—— 昵称"万星瞳"的宽视场X射线望远镜(WXT)和昵称"风行天"的后随X射线望远镜(FXT)。 0:00 / 1:13 视频来源:中国科学院国家天文台 来自中国科学院国家天文台的最新消息说,天文学家通过对中国天关卫星(爱因斯坦探针,英文缩 写EP)巡天捕获的、编号为EP250702a的高能宇宙爆发事件的最新研究,认为它很可能是一个中等质量 黑洞撕裂并吞噬一颗白矮星的过程。 国际学界对EP250702a事件的起源意见不一,有研究提出,它可能源于恒星质量黑洞与一颗氦星的 并合;有模型考虑恒星级黑洞撕裂普通恒星的可能性。 天关卫星科学团队总结说,EP250702a这一中等质量黑洞以喷流 ...
