SN 2023ixf:十年来最近的超新星

SN 2023ixf: The Closest Supernova of the Decade

W. V. Jacobson-Galán

AI总结:

本文综述了十年来最近的 II 型超新星 SN 2023ixf 的多波段观测研究,揭示其与红超巨星流失的星周物质的相互作用,并探讨其对超新星爆炸物理和恒星晚期质量流失历史的限制。

摘要:

超新星 2023ixf 发生于 2023 年 5 月 18 日,位于附近的星系 Messier 101(D ~ 6.85 Mpc),使其成为过去十年中最近的超新星。发现之后,世界各地的天文学家竞相在整个电磁波谱上观测这次爆炸,以揭示其早期性质。基于爆炸后第一年的多波长分析,超新星 2023ixf 是一颗 II 型超新星,它与其局部环境中的致密、受限的星周物质发生了相互作用——这些物质是其红超巨星前身在爆炸前的最后几年中流失的。在本文中,我们将回顾已发表的关于这一惊人事件的 >80 项研究,并探讨如何综合整个电磁波谱上的 SN 2023ixf 观测结果,以限制 II 型超新星爆炸物理学以及红超巨星在最后几年中不确定的质量流失历史。

英文摘要:

Supernova 2023ixf occurred on May 18th 2023 in the nearby galaxy Messier 101 (D ~ 6.85 Mpc), making it the closest supernova in the last decade. Following its discovery, astronomers around the world rushed to observe the explosion across the electromagnetic spectrum in order to uncover its early-time properties. Based on multi-wavelength analysis during its first year post-explosion, supernova 2023ixf is a type II supernova that interacted with dense, confined circumstellar material in its local environment -- this material being lost from its red supergiant progenitor in the final years before explosion. In this article, we will review the findings of >80 studies already published on this incredible event as well as explore how the synthesis of SN 2023ixf observations across the electromagnetic spectrum can be used to constrain both type II supernova explosion physics in addition to the the uncertain mass loss histories of red supergiant stars in their final years.
