Ground-based light curve follow-up validation observations of TESS object of interest (TOI) 3737.01

Abstract: NASA’s Transiting Exoplanet Survey Satellite (TESS) mission aims to discover new exoplanet candidates by detecting periodic dips in starlight as potential candidates. TOI-3737.01 was flagged as one due to having an observed periodic dip in stellar brightness, which could indicate a transiting exoplanet. To investigate the possibility of false positives such as NEBs (nearby eclipsing binaries), an observation was conducted with telescopic evidence at GMU’s Observatory. From this data, a light curve was produced using multi-aperture photometry. The status of TOI-3737.01 as an exoplanet candidate can be evaluated by matching the predicted transit window from TESS with a dip in brightness on the light curve. This follow-up study provides ground-based & analyzed photometric evidence that supports the classification of TOI-3737.01 as an exoplanet candidate. Even so, deeper observations are still required to rule out false positives. This work is important because confirming/eliminating these candidates helps improve the accuracy of TESS detections and guides future observations. TOI-3737.01 has a predicted planetary radius of ~15.3 Earth radii and orbits a host star about 1.58 times the Sun’s radius, making it a promising target for giant planet studies.
