摘要

在本文中，我们分析并解释了利用 HST 望远镜观测系外行星 HD 189733b 穿越恒星盘面所获得的光变曲线。观测是在 5500-10500 Å 的宽波长范围内进行的，这使得在解释行星半径的过程中确定波长与所获数据之间的关系成为可能。观测结果还表明，这种依赖关系可以用行星上存在的雷利大气层来解释，同时还对这种大气层的可能参数进行了近似估算。

Determining the Structure of the Atmosphere Exoplanet HD 189733b Based on Multicolor Photometric Transit Observations

In this paper, we analyze and interpret light curves obtained by observing with the HST telescope the transit of exoplanet HD 189733b across the disk of the star. Observations are carried out in a wide wavelength range of 5500–10 500 Å, which makes it possible to identify the relation between the wavelength and the data obtained during the interpretation of the radius of the planet. It is also shown that this dependence can be explained by the presence of a Rayleigh atmosphere on the planet while the possible parameters of this atmosphere are also approximately estimated.
