Abstract
The Transiting Exoplanet Survey Satellite (TESS) mission gathers data for thousands of candidate exoplanets and their host stars (Zhang et al., 2022). In this paper we present research of TOI 3553, which is orbited by candidate exoplanet TOI 3553.01. The goal of this paper is to provide a ground based follow up of the planetary nature of TOI 3553.01. We also will confirm if TOI 3553 is a near eclipsing binary (NEB). We took 303 exposures with the GMU 0.8 m telescope and reduced them, then we conducted ground based multi aperture photometry using AstroImageJ to generate a light curve. Lastly, we conducted an NEB analysis on TOI 3553. We determined that TOI 3553.01 is not a near eclipsing binary. Due to the fact that the transit did not happen during the expected time, we did not confirm the planetary nature of TOI 3553.01.
