冰巨星大气研究进展
Research Progress on the Atmosphere of Ice Giant Planet
摘要
Abstract
The giant planets being mainly composed of elements heavier than hydrogen and helium are defined as ice giant planets. The Uranus and Neptune are two typical ice giant planets in the solar system. Since the atmosphere of ice giant preserves the earliest gas when solar system formed, it would be great help to understand the formation and evolution of the planetary system. Study on the dynamics of the atmosphere can reveal the structure, convection mechanism and its thermal driving of the atmosphere. How different kinds of planets are ultimately generated from an initial primordial cloud of gas and dusts can be explored by a comparative study between the ice giant planets and Jupiter-like planets. The Neptune-like exoplanets are found to be ubiquitous from more and more exoplanets identified during the recent years, which provide a strong observation evidence for planetary migration theories. The ice giant planets not only play important role in the early stage of the formation of stellar system, but also their atmospheric compositions are important parameters in the study of their host stars. This paper reviews the research progress on the atmospheres of Uranus and Neptune, including the vertical thermal structure, chemical composition and wind distribution with latitude. The ice giant planets of the extrasolar systems are also discussed. Challenges and future observation are suggested based on our current understanding of the ice giant planets.关键词
