High-precision follow-up of transit-timing variation of WASP-10b

对凌日系外行星的光度跟踪可能会导致在一个系统中发现另一个低质量天体。这可以通过探测和分析凌日系外行星凌日时间的变化来实现。我们观测到系外行星wasplb的凌日时间不能用常数周期来解释，而是用周期变化来解释。假设系统中存在扰动行星并再现观测到的时间残差变化的模型被考虑。由于不同的行星构型产生相似的TTV信号，具有相同的主周期，我们打算在观测到的时间变化的关键阶段收集高精度观测数据，以部分消除简并并指出WASP-10系统最可能的行星构型。

Photometric follow-ups of a transiting exoplanet may lead to discovery of another lowmassbody in a System. This is possible by detecting and then analysing variations intransit timing of the transiting exoplanet. We observed transit timing of exoplanet WASPlObwhich cannot be explained by a constant period but by a periodic Variation. Modelsassuming the existence of a perturbing planet in the System and reproducing the observedvariations of timing residuals are considered. As different planet configurations generatesimilar TTV Signals with the identical dominant periodicity, we intend to collect highprecisionobservations in critical phases of observed timing Variation to partially remove thedegeneracy and to point out the most probable planet configuration of WASP-10 System.
