中国的天川卫星探测到一个罕见的X射线爆破,它来自一个可能干扰白矮星的中间质量黑洞。 China’s Tianguan satellite detected a rare X-ray burst from a likely intermediate-mass black hole disrupting a white dwarf.

中国天川卫星于2025年7月2日探测到一种稀有的X射线爆破,即EP250702a,可能来自一个中质量黑洞,该黑洞撕裂了一个白矮星。 China's Tianguan satellite detected a rare X-ray burst, EP250702a, on July 2, 2025, likely from an intermediate-mass black hole tearing apart a white dwarf star. 这个事件的极端亮度、短时间和软X射线后光不同于已知的超新星或典型的潮汐干扰,这表明一个稠密的恒星残余物受到撞击。 The event’s extreme brightness, short duration, and soft X-ray afterglow differ from known supernovae or typical tidal disruptions, suggesting a jetted disruption of a dense stellar remnant. 只有中质量黑洞 — — 太阳质量的百至数十万倍 — — 才能产生必要的潮汐力量。 Only intermediate-mass black holes—hundreds to hundreds of thousands of times the Sun’s mass—can generate the necessary tidal forces. 这标志着对此类事件的首次潜在观测,展示了卫星捕捉不可预测的宇宙现象的能力,突出了中国在空间天文学中日益重要的作用。 This marks the first potential observation of such an event, showcasing the satellite’s ability to capture unpredictable cosmic phenomena and highlighting China’s growing role in space-based astronomy.
