We performed follow-up photometric observations on exoplanetary system HAT-P-37 from 2011 February to 2019 September. The nine new transit light curves of the R and V bands are presented in this work. Based on the new light curves and published literature data, the physical and orbital parameters of HAT-P-37 are refined. In addition, mid-transit times are obtained to update the linear ephemeris, Tc[0] = 2456478.57916 ± 0.00077 [BJDTDB], P = 2.7974415 ± 0.0000025 d. Moreover, the transit timing variations (TTVs) have an rms of 57 s and there is no significant TTV signal. According to dynamic analysis, we excluded the possibility of perturbers with a mass larger than 200M⊕, when located in 1 : 3, 1 : 2, 2 : 3 (interior) or 3 : 2, 2 : 1, 5 : 2, 3 : 1 (exterior) orbital resonance, respectively.

HAT-P-37b的光度跟踪观测和凌日时间分析

我们于 2011 年 2 月至 2019 年 9 月对系外行星系统 HAT-P-37 进行了后续光度观测。在这项工作中呈现了 R 和 V 波段的九个新的光变曲线。根据新的光变曲线和已发表的文献数据，对 HAT-P-37 的物理和轨道参数进行了细化。此外，还获得了更新线性星历的中途时间，Tc[0] = 2456478.57916 ± 0.00077 [BJDTDB]，P = 2.7974415 ± 0.0000025 d。此外，传输时间变化 (TTV) 的 rms 为 57 s，并且没有明显的 TTV 信号。根据动态分析，我们排除了质量大于 200M⊕ 的扰动体，当位于 1:3、1:2、2:3（内部）或 3:2、2:1、5:2、3 : 1 (外部) 轨道共振，分别。
