摘要

本文介绍了系外行星系统HD 189733、HAT-P-13、HAT-P-16和HAT-P-65的研究结果。对所列系统的系外行星凌日进行了蓝、红两色分光光度观测，观测仪器为俄罗斯科学院高加索山天文台和俄罗斯科学院克里米亚天文台。根据结果，绘制出了光曲线，并据此确定了系外行星的半径。在不同滤光器中显示的系外行星半径的差异可能表明所研究的系外行星中存在大气。

Searching for Traces of Exoplanet Atmospheres Using Multicolor Photometric Observations of Transits

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.
