Abstract

The paper presents the results of study of the exoplanet systems HD 189733, HAT-P-13, HAT-P-16 and HAT-P-65. The multi-color photometric observations of exoplanet transits in the listed systems were carried out in blue and red rays using the equipment of the Caucasian Mountain Observatory and the Crimean Astronomical Station of the SAI MSU. Based on the results, light curves were plotted, from which the radii of the exoplanets were determined. The shown difference in the radii of the exoplanets in different filters may indicate the presence of atmospheres in the exoplanets under study.
