太阳系卫星与冥王星的大气层

Atmospheres of Solar System Moons and Pluto

Xi Zhang

AI总结:

该研究将太阳系大气层分为四类,综述了木卫一、土卫六、海卫一、冥王星等小天体碰撞大气层的特征与物理化学机制,明确了表面冰液、霾层和宿主行星空间环境的关键作用。

摘要:

太阳系内的大气层可分为四种不同的气候类型:“类地型”“类木型”“可凝缩型”和“外逸层型”。除三颗类地行星(不含水星)和四颗巨行星外,在木星卫星Io(木卫一)、土星卫星Titan(土卫六)、海王星卫星Triton(海卫一)以及冥王星等较小天体上也存在碰撞大气层。本文综述了这些大气层的关键特征及支配其演化的基础物理与化学过程。研究聚焦于它们的热结构、化学成分、风场模式以及大气的起源与逃逸机制,并强调了表面冰与液体、大气霾层以及宿主行星的空间环境在塑造这些大气层过程中的关键作用。本文谨献给北京大学左肖教授(1936-2024)。

英文摘要:

The atmospheres within our Solar System can be categorized into four distinct climate regimes: "terrestrial", "Jovian", "condensable", and "exosphere". Beyond the three terrestrial planets (excluding Mercury) and the four giant planets, collisional atmospheres are also found on smaller celestial bodies such as Jupiter's moon Io, Saturn's moon Titan, Neptune's moon Triton, and Pluto. This article reviews the key characteristics of these atmospheres and the underlying physical and chemical processes that govern them. I focus on their thermal structures, chemical constituents, wind patterns, and the origins and losses of the atmospheres, and highlight the critical roles of surface ices and liquids, atmospheric hazes, and the space environments of their host planets in shaping these atmospheres. I dedicated this article to Prof. Zuo Xiao (1936-2024) at Peking University.
