A Uniform Analysis Of Exoplanet Atmospheres: Transmission and Emission Measurements
Abstract
We will perform the first comprehensive uniform analysis of Exoplanet transmission and emission spectral measurements obtained with the best facilities to date for these observations by leveraging the combined potential of Hubble and Spitzer. The broad wavelength range achieved by combining observations from these two Great Observatories offers the best possible characterization of exoplanet atmospheres. The scope of this study is large, including over 75 individual planets, ranging from hot Jupiters to temperate super Earths. Our uniform analysis of these data will permit the first comprehensive comparative planetology study of this diverse sample and allow statistical measurements of important properties of the exoplanet population that probe the planet formation process through the mass-metallicity relation and the star/planet C to O ratio. Our study will also provide important contextual information about the exoplanet population, such as trends or likelihood of specific spectral features, necessary for making optimal use of the James Webb Space Telescope for exoplanet studies. To best support the broader community s use of James Webb, our effort and data management plan is structured to rapidly deliver and disseminate actionable results.
