Schematic of the circum-Jovian decretion disk. Gas and dust from the circumsolar accretion disk are subsumed into the Jovian disk from approximately one hydrostatic scale height via meridional flows, and

Dayside temperature scaling factor, R = Tday/Tday,max, as a function of irradiation temperature, Tirr, for (a) all observed rocky exoplanets and (b) planets with Tirr > 1500 K, which may
