论文摘要

当行星体在星前(包括我们的太阳)时,会发生恒星的仿生和过渡。对于具有大气的物体,折射起着解释在这些事件中观察到的通量和金黄色的滴剂的重要作用。这可用于得出大气的关键参数,例如它们的密度,压力和温度曲线,以及大气重力波和纬向风的存在。在这里,我们从基本原理中得出了统治行星大气中射线传播的方程式,并展示了它们如何用于得出这些大气的物理参数。

Stellar occultations and transits occur when a planetary body passes in front of a star (including our Sun). For objects with an atmosphere, refraction plays an essential role to explain the drops of flux and the aureoles observed during these events. This can be used to derived key parameters of the atmospheres, such as their density, pressure and temperature profiles, as well as the presence of atmospheric gravity waves and zonal winds. Here we derive from basic principles the equations that rule the ray propagation in planetary atmospheres, and we show how they can be used to derive the physical parameters of these atmospheres.
