Abstract
Abstract
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.
