Ground-Based Light Curve Follow-up Validation Observations of Tess Object of Interest TOI 5352.01

The study of exoplanets is a rapidly expanding field that has captivated astronomers worldwide. NASA’s Transiting Exoplanet Survey Satellite (TESS) mission contributes to this by identifying exoplanet candidates through the detection of periodic dips in stellar brightness caused by planetary transits (https://exoplanets.nasa.gov/tess/ ). However, the vast amount of data produced by TESS makes it difficult to thoroughly investigate each candidate. The aim of this research is to provide targeted follow-up observations of ground-based light curves. These observations enable in-depth analysis to help confirm and characterize promising exoplanet signals. We applied the data reduction techniques of flat and dark calibration in AstroImageJ to process scientific images (Collins et al., 2017). We then aligned and plate-solved the images from the George Mason University Observatory. AstroImageJ was then used to generate a light curve and perform NEB analysis (Plavchan et al., 2020). No stars flagged as inconclusive in the NEB analysis were close enough to the target star to interfere with its light curve. The target’s light curve suggests that TOI 5352.01 is not an exoplanet due to the absence of a drop in the light curve at the expected time and at the expected depth.
