A Search For Trends In The Atmospheric Composition Of Exoplanets From Archived Spectral Data

Troy Maloney

Abstract


The study of exoplanets has produced large amounts of data since the first exoplanet was discovered over two decades ago. Much of these data, specifically transmission spectroscopy data, are available online to be reused to search for new results. Transmission spectroscopy is a widely used method of determining the composition of exoplanet atmospheres. The goal of this study is to gather transmission spectroscopy data from the literature on many different exoplanets to search for trends in the composition of their atmospheres. Many atmospheric studies produce data from single planets, but few search for trends across multiple planets. We will focus on hot Jupiter type planets because they transit their parent stars often, their atmospheres absorb a large portion of the stellar flux, and thus spectral data on these types of planets is the most abundant. This literature review will produce a compilation of data that will be convenient to researchers who require spectral data for their atmospheric studies.
