Abstract

We present photometric observations and transit solutions of the exoplanets XO-2b, HAT-P-18b and WASP 80b. Our solution of the XO-2b transit gave system parameters whose values are close to those of the previous studies. The solutions of the new transits of HAT-P-18b and WASP 80b differ from the previous ones by bigger stellar and planet radii. We obtained new values of the target initial epochs corresponding to slightly different periods. Our investigation reaffirmed that small telescopes can be used successfully for the study of exoplanets orbiting stars brighter than 13 mag.

凌日外行星XO-2b、HAT-P-18b和WASP-80b的观测和建模

本文介绍了系外行星XO-2b、HAT-P-18b和WASP 80b的光度观测和凌日解。我们对XO-2b凌日的解给出的系统参数值与前人的研究结果接近。HAT-P-18b和WASP 80b新凌日的解与之前的解不同，恒星和行星半径更大。我们得到了目标初始期的新值，对应于略有不同的时期。我们的研究再次证实，小型望远镜可以成功地用于研究围绕13等以上恒星运行的系外行星。
