Transit Analysis of Exoplanets TrES-5 b and WASP-43 b with the EXOplanet Transit Interpretation Code

Abstract

Abstract In this study, we analyze light curves and corresponding transit attributes of the exoplanets TrES-5b and WASP-43b. The mid-transit time of an exoplanet is the time in which the planet is in the middle of its transit. Over time, due to variations that arise after many periods, the error in the mid-transit time of the exoplanet increases. Because of this, constant observations of exoplanet mid-transit times through light curves are necessary to update the transit timing predictions. We made light curves with the EXOplanet Transit Interpretation Code (EXOTIC). To run with EXOTIC, we were given raw, uncalibrated TrES-5b images taken by the SRO telescope, managed by the Boyce-Astro project. Additionally, we requested and obtained images of WASP-43b using the Las Cumbres Observatory 0.4 m robotic telescopes. Within this work, we will explore the newly calculated mid-transit times and other transit properties to gain a better understanding of TrES-5b and WASP-43b.
