- Abstract
- The paper presents an analysis of high-precision satellite light curves of exoplanets HD 189733 b and HD 209458 b. The dependence of the exoplanet radius on the wavelength caused by scattering in the planetary atmosphere is determined using a four-parameter limb darkening law based on a three-dimensional model of the stellar atmosphere. It is shown that when using the same exoplanet system characteristics for all wavelengths, primarily the orbital inclination, as well as when using a four-parameter law with a refined radius of the star, the change in the radius of the exoplanet HD 189733 b with increasing corresponds to the model of an exponential Rayleigh atmosphere with a characteristic height of 380–400 km. At the same time, the characteristics of the atmosphere of HD 209458 b largely depend on the adopted eccentricity of the system.
