Models of potential transmission spectra of Kepler-167e. Gray regions denote Kepler and Spitzer-IRAC Channel 1 bandpasses. Top: spectra modeled using Exo-Transmit. The 13 MJupiter spectrum is consistent with the Spitzer transit depth and the others are offset for clarity. The CH4 absorption between 1 and 2 μm and the deep window at 5 μm points to the potential benefit of conducting joint HST-JWST transmission spectroscopy. Bottom: spectrum based on Saturn (Dalba et al. 2015) but scaled to the properties of Kepler-167e. The 3.4 μm feature is partially due to opacity from CH4 photochemical byproducts. The potential to detect an active methanological in Kepler-167e’s atmosphere motivates additional modeling and future near-infrared transmission spectroscopy.
