Detecting and Monitoring Tidal Dissipation of Hot Jupiters in the Era of SiTian

Transit Timing Variation (TTV) of hot Jupiters provides direct observational evidence planet tidal dissipation. Detecting dissipation through TTV needs high precision transit timings and long timing baselines. In this work, we predict discuss the potential scientific contribution SiTian Survey in detecting analyzing exoplanet TTV. We develop a detection pipeline for that aims at time-domain astronomy with 72 1-meter optical telescopes. The includes modules light curve deblending, obtaining, modeling. is capable to detect more than 25,000 exoplanets among which expect $\sim$50 sources showing present analysis dissipating targets, based on simulated curves XO-3b WASP-161b. modeling gives consistent results within 1$\sigma$ input values curves. Also, parameter uncertainties predicted by Monte-Carlo Markov Chain are distribution obtained from simulating 1000 times. observations $\sim$ 0.5 minutes one visit. show differences between origins, e.g., dissipation, apsidal precession, multiple planets, would be significant, considering baseline. rate answer crucial question whether migrates an early formation stage or random stages due perturbations, scattering, secular interaction. identified targets constructive given sample extend tenfold.
