Abstract
Discovered by the Transiting Exoplanet Survey Satellite, TOI-4994 has been identified as likely hosting a planet. I use a method to analyze and characterize TOI-4994b using the PHysics Of Eclipsing BinariEs program, with archival data from the Transiting Exoplanet Survey Satellite, High Accuracy Radial velocity Planet Searcher, and the Planet Finder Spectrograph. I will present the radii and masses of TOI-4994b and its host star as well as the inclination and eccentricity of the system by analyzing the photometry and radial velocity data. Then I will compare those results to those found with the exoplanet modeling software, EXOFAST.
