TESS has provided a wealth of photometric data, but ground-based observations are essential to refine parameters and confirm planetary candidates. Aims: Our primary goal is to enhance the understanding of a TOI by conducting a meticulous ground-based follow-up. Through precise light curve analysis, we aim to confirm the planetary nature of TOI and refine its orbital parameters, ultimately contributing to the characterization of a possible exoplanet. Methods: We collected high-quality ground-based photometric data using observatory telescopes and instruments. By reducing and analyzing these data, we carried out a light curve analysis to validate TOI's planetary status.enCopyright 2023 William YangProject
