项目摘要
We formulated light propagation in the atmospheres of exoplanets in transit and derived a formula of an angle of refraction for light rays propagating through the atmosphere. The formula provides precise values even for the rays incident with small impact parameters onto the atmosphere. We proposed a method of estimating a scale height of an atmosphere from a light curve at a transition of an exoplanet in front of a central star. Systematic calculations of ray tracing are carried out for the rays passing through model atmospheres under isothermal hydrostatic equilibrium with varying wavelength of the light rays, and discussion was made on apparent increase in the radius of a planet in transition. The results are applied to the observation of Galilean satellites, which are observed through the atmosphere of Jupiter. Analysis of the observation indicates that the theory roughly explains the observation but suggests the presence of some effect that is not taken into account in the theory.
我们制定了光在过境的系外行星的大气中的传播,并推导出一个公式的折射角的光线通过大气传播。该公式提供了精确的值,即使是对入射到大气中的小的影响参数的射线。我们提出了一种方法,估计大气层的尺度高度的光变曲线在中央星星前面的过渡的系外行星。本文系统地计算了不同波长光线通过等温流体静力平衡模式大气的光线追迹,并讨论了过渡行星半径明显增大的现象。将结果应用于伽利略卫星的观测,通过木星的大气层进行观测。对观察结果的分析表明,理论大致解释了观察结果,但表明存在一些理论中没有考虑到的效应。
