天文学家首次捕捉了两个新星的详细图像,揭示了复杂的、分阶段的流出和冲击驱动的伽马射线,从而改变了对恒星爆炸的理解。 Astronomers captured first detailed images of two novae, revealing complex, staged outflows and shock-driven gamma rays, reshaping understanding of stellar explosions.

使用CHARA阵列的天文学家在两次新星(V1674 Herculis和V1405 Cassiopeiae)的喷发后不久,首次捕捉了这两处新星(V1674 Herculis和V1405 Cassiopeiae)的高分辨率图像,揭示出复杂的多阶段流出现象。 Astronomers using the CHARA Array captured the first high-resolution images of two novae, V1674 Herculis and V1405 Cassiopeiae, shortly after their eruptions, revealing complex, multi-phase outflows. 图像显示了一个新星中垂直的气体喷流,与NASA的费米望远镜探测到的马射线发射有关,而另一个则延迟了50多天的外层喷射,产生了后来的冲击和马射线. The images show perpendicular gas jets in one nova, linked to gamma-ray emission detected by NASA’s Fermi Telescope, while the other delayed outer-layer ejection for over 50 days, producing later shocks and gamma rays. 这些结果发表在2025年12月5日的《自然天文学》上,挑战了将新星作为简单爆炸的长期观点,而不是显示它们涉及动态的、分阶段的抛射和强大的冲击互动,增进了对恒星爆发和多信号天文学的理解。 These findings, published in Nature Astronomy on December 5, 2025, challenge the long-held view of novae as simple explosions, instead showing they involve dynamic, staged ejections and powerful shock interactions, advancing understanding of stellar outbursts and multi-messenger astronomy.
