AI 中文摘要
彗星C/2023 A3（紫金山-ATLAS）是一颗非周期性的动态新奥尔特云彗星，由中国紫金山天文台和南非小行星地面撞击最后警报系统（ATLAS）望远镜独立发现。该彗星于2024年9月27日在距离近日点0.39天文单位处经过，肉眼可见（是自C/1995 O1（海尔-波普）彗星以来最亮的），被称为2024年的大彗星。在这项工作中，我们通过使用各种观测技术分析其成分，并通过高精度N体模拟追踪其轨道演化，来研究这颗在双曲线轨道（e>1）上运行的彗星的本质。
英文摘要
Comet C/2023 A3 (Tsuchinshan-ATLAS) is a non-periodic dynamically new Oort cloud comet that was discovered independently by Purple Mountain Observatory in China and Asteroid Terrestrial-impact Last Alert System (ATLAS) telescopes in South Africa. The comet passed perihelion at a distance of 0.39 AU on 27 September 2024. It was visible to the naked eye (the brightest since the comet C/1995 O1 (Hale-Bopp)) and was dubbed the great comet of 2024. In this work, we investigate the nature of this comet, which is moving in a hyperbolic orbit (e > 1), by analysing its composition using various observational techniques and tracing its orbital evolution through high-precision N-body simulations.
