Abstract

The transit method, with over 4000 confirmed exoplanets to date, remains one of the most prolific and robust techniques in the field. This study focuses on the WASP-10 system, a K5-type star located 92 parsecs from Earth, which hosts the confirmed exoplanet WASP-10b. We present a detailed analysis of data from the TESS and TASTE surveys to characterize the planetary parameters of WASP-10b and compare them with values reported in the literature. Although both surveys employ the transit method, their observational strategies and data reduction pipelines differ substantially. Consequently, the datasets were processed independently and subsequently analyzed using a Markov Chain Monte Carlo (MCMC) framework to determine the orbital and physical parameters that best reproduce the observed light curves.
