Measuring exoplanetary radii using transit photometry

Sarah Tang, Colorado, USA 13-15

Exoplanets are planets that orbit a star other than the Sun. The study of exoplanets allows for further understandings regarding planet populations, the formation of planets, and the interactions between planets. Exoplanets can be detected through planetary transits, which occur when a planet crosses the disk of its host star and causes a dimming in the detected amount of light emitted from the host star from the observer's viewpoint. In my project, I studied the transit light curves of three hot Jupiter exoplanets (HAT-P-25b, HAT-P-9b, and HAT-P-30b) in order to measure their radii and constrain their orbital periods.
