NASA的IXPE解开了历史上第谷超新星的谜团
一个国际科学家团队发现了450年前发现的一颗恒星爆炸残骸的新信息。这一结果为超新星爆炸产生的冲击波如何将粒子加速到接近光速提供了新的线索。 这颗超新星遗迹被称为第谷，以丹麦天文学家第谷·布拉尼的名字命名，他在1572年注意到仙后座中这颗新“恒星”发出的明亮光芒。在这项新的研究中，天文学家使用NASA的X射线偏振成像探测器（IXPE）研究第谷超新星遗迹的偏振X射线。 利用NASA X射线偏振成像探测器（IXPE）的数据，国际研究人员发现了第谷超新星残骸的新信息，第谷超巨星残骸是仙后座的一颗爆炸恒星，1572年首次在地球上看到它发出的光。这些结果为这些巨大的恒星爆炸产生的冲击波如何将粒子加速到接近光速提供了新的线索，并首次揭示了超新星爆炸波附近磁场的几何结构，如这张合成图像所示，爆炸波在喷射物质周围形成了一个边界。...
