Abstract We report photometric follow-up observations of WASP-135b obtained using the 1.23-m telescope at Calar Alto Observatory and 1.00-m telescope at TUBITAK National Observatory during the 2017 and 2018 observational seasons. Eight new transit light curves of WASP-135b were analyzed with jktebop code. The ratio of the planet radius to radius of host star, fractional radius of host star, and orbital inclination of WASP-135b were found to be 0.138 ± 0.002, 0.181 ± 0.008 and 82.44 ± 0.64 degrees, respectively. Planetary radius of WASP-135b was derived from transit parameters to be 1.075 ± 0.150 RJ. The transit ephemeris of WASP-135b was also updated using the maximum likelihood method (MLM). 165 well-known hot Jupiters (HJs) were selected from the Exoplanet Data Explorer database and the classification of these HJs together with WASP-135b, based on their equilibrium temperatures and Safronov numbers, is discussed.

热木星的新光度分析:WASP-135b

摘要 我们报告了在 2017 年和 2018 年观测季节期间使用 Calar Alto 天文台的 1.23 米望远镜和 TUBITAK 国家天文台的 1.00 米望远镜获得的 WASP-135b 的光度跟踪观测。使用 jktebop 代码分析了 WASP-135b 的八种新传输光变曲线。发现行星半径与主星半径的比值、主星的分数半径和 WASP-135b 的轨道倾角分别为 0.138±0.002、0.181±0.008 和 82.44±0.64 度。WASP-135b 的行星半径从传输参数推导出为 1.075 ± 0.150 RJ。WASP-135b 的过境星历也使用最大似然法 (MLM) 进行了更新。从 Exoplanet Data Explorer 数据库中选择了 165 个著名的热木星 (HJ),并将这些 HJ 与 WASP-135b 一起分类,
