GJ 367b Is a Dark, Hot, Airless Sub-Earth

We present the mid-infrared (5–12 μ m) phase curve of GJ 367b observed by the Mid-Infrared Instrument on the James Webb Space Telescope (JWST). GJ 367b is a hot ( T _eq = 1370 K), extremely dense (10.2 ± 1.3 g cm ^−3 ) sub-Earth orbiting an M dwarf on a 0.32 day orbit. We measure an eclipse depth of...
