Ground-based light curve follow-up validation observations of TESS object of interest TOI 6347.01

NASA’s MIT-led mission to detect exoplanets, Transiting Exoplanet Surveillance Satellite (TESS), created in 2018, has already gathered data to map more than 93% of the night sky (1). To date the mission has confi rmed 687 exoplanets, with 7668 candidates (2). This ground-based observational study aims to verify the status of TESS Object of Interest (TOI) 6347.01, along with the nature of its existence. The TESS mission has identifi ed this object as an exoplanet candidate, yet it currently lacks evidence and analysis necessary for confi rmation. This study aims to detect the exoplanet through transit photometry with AstroImageJ (AIJ) to perform multi-aperture photometry on the 200 exposures taken using George Mason University’s 32” Ritchey-Chretien Cassegrain refl ector, using an SBIG-STX 1608 CCD within the observatory. Additionally, we conducted a Near Eclipsing Binary (NEB) check to verify that the transit caused was truly due to the planet, not a binary star close to the TOI. A clear transit at the expected times with the expected depth for TOI 6347.01 was ultimately not found, and as our NEB check was inconclusive, we cannot rule out the possibility of a false positive.
