Mid-Term Report Summary - CREATES (Classifying the Range of Exoplanetary Atmospheres using Transmission and Emission Spectroscopy)

This project uses a twofold approach to advance both the theory and observation of exoplanets beyond their current limitations. The hot Jupiter atmospheric spectra build upon two large observational survey programmes headed by Dr. Sing, one large programme uses the Hubble Space Telescope which is augmented by a large programme on the 10.4-m GTC telescope. Both large programmes are further complemented by followup observations, as well as existing near-IR spectroscopy from HST and Spitzer. This project aims at combing the data in a coherent fashion, enabling studies of nearly the entire planetary atmosphere, including both the lower, middle and upper atmospheres as well as dayside and terminator regions. Our observational efforts are combined with a broad and inclusive theoretical modelling programme, aimed at incorporate a full range of crucial physical effects together, including notably clouds and hazes, modelling the complete atmosphere in a self-consistent manner with a 3D global circulation model. Our observational results will provide legacy transmission spectra across the hot-Jupiter exoplanetary class and will be used to address long outstanding and complex issues. The project aims at two key scientific contributions, addressing why some hot Jupiters have hazes & clouds while others do not, and the outstanding issue on the presence or absence of stratospheres. A major goal of the programme is to develop the comparative exoplanetary atmospheric science; where for the first time a uniform and comprehensive set of high quality exoplanet spectra will be available with which to inter-compare using the required set of theoretical tools.
