Inspecting Cloudy Substellar Atmospheres with JWST MIRI Synthetic Magnitudes from Spitzer Mid-infrared Spectra

We examine the positions of substellar objects in mid-infrared color–magnitude and color–color diagrams to distinguish between cloudy and cloud-free atmospheres. Using Spitzer mid-infrared spectra of 113 M5–T9 ultracool dwarfs, we derive synthetic photometry for the JWST Mid-Infrared Instrument (MIR...
