SGER: Theory for Satellite Coronae and Atmospheric Escape

行星日冕的经典描述是由J.W.张伯伦在1963年建立的，日冕是大气中流体流动问题从碰撞介质过渡到非碰撞介质的区域。非碰撞玻尔兹曼方程的解是航空学历史上的一项开创性成就，它描述了轻气体从行星大气中逸出，并通过直接推广提供了一个框架，通过该框架，行星大气的演变可以分析量化。这个项目将分析处理从二体（行星，原子）形式主义扩展到三体（行星，卫星，原子）形式主义。这一扩展有望第一次真实地描述卫星大气的结构和演变（在我们的太阳系中有11个这样的大气），并从根本上改进地球外逸层的分析模型，因为日冕是太阳-地球-原子三体问题的恰当表现。

The classical description of planetary coronae - that region of the atmosphere wherein the fluid flow problem transitions from a collisional to a non-collisional medium - was established by J.W. Chamberlain in 1963. That solution of the non-collisional Boltzmann equation stands as a seminal achievement in the history of Aeronomy, describing the escape of light gases from planetary atmospheres and by direct extension providing a framework by which the evolution of planetary atmospheres could be analytically quantified. This project expands that analytical treatment from a two-body (planet, atom) formalism to a three-body (planet, satellite, atom) formalism. That expansion promises the first realistic description of satellite atmosphere structure and evolution (there are 11 such atmospheres identified in our solar system), as well as a fundamental improvement in the analytical model of the Earth exosphere, since that corona is properly the manifestation of the Sun-Earth-atom three-body problem.
