Analysis of Eclipsing Binary Stars and Identification of Exoplanets Using Transit Timing Variation Using data from TESS

Abstract

This study uses openly available TESS (Transiting Exoplanet Sky Survey) data to detect evidence for potential exoplanet transits in an eclipsing binary system. Using the Python transit light curve analysis package lightcurve, we discuss the characteristics of an eclipsing binary star’s light curve in determining the classification of a system. In addition, we also study phenomena on a light curve that indicates the existence of a potential exoplanet. Although this investigation yields null results and finds no conclusive evidence, suggesting the presence of exoplanet transits in known eclipsing binaries using TESS data, we explored in depth the physical properties of binary star system TIC 7720507, identifying strong methods for explanatory stellar research.
