Abstract
The work carried out an analysis and interpretation of light curves obtained with observing with the HST telescope the transit of the exoplanet HD 189733 b across the disk of the star. Observations were carried out in a wide range of wavelengths 5500–10500 Å, which made it possible to identify the relationship between the wavelength and the data obtained during the interpretation of the radius of the planet. It has also been shown that this dependence can be explained by the presence of a Rayleigh atmosphere on the planet, and an approximate assessment of the possible parameters of this atmosphere was also carried out.
