Task Description and Goals

The majority of the light curves produced by the Transiting Exoplanet Survey Satellite (TESS) mission are 27.4 days in length. This is a rich dataset, but from a planet hunting perspective these light curves are primarily useful for identifying planets with short-period orbits. Fortunately, TESS observed two regions of the sky -- the Continuous Viewing Zones (CVZs) -- for a full year, and in these fields there is the possibility of finding planets at significantly greater distances from the host star. These cooler planets, we have reason to believe, are especially attractive targets in the search for exomoons. In this project, the student will obtain, filter, and analyze Full-Frame Image light curves from the CVZ (a largely untapped dataset consisting of roughly half a million light curves) to identify new planet candidates, with a particular focus on finding systems that are appropriate targets for a future exomoon survey. For the stars under consideration we will attempt to identify possible transit signals, characterize the host star, remove data systematics, and fit transit models to the data, with the aim of producing a catalog of systems worthy of follow-up.
