Determination of the sizes of exoplanets using light curves

Abstract

This dissertation presents a study of the determination of exoplanet sizes using light curves derived from space-based observations, specifically data from the Transiting Exoplanet Survey Satellite (TESS). By analyzing the transit method and applying open-source tools such as the Plight curve and Lightkurve, i demonstrate a method for extracting planetary radii from photometric data, using the exoplanet WASP-12b.This work demonstrates the application of the transit method in exoplanetary science, underscoring its effectiveness in producing scientifically relevant results. The study highlights the importance of reproducibility in astronomical observations and the contributions of modern missions in advancing our understanding of exoplanets.
