Radiative budget of atmosphere of our five lava planets. The first column shows the absorption of stellar flux, the second shows the absorption of blackbody radiation from the surface, and the third shows radiative cooling. K2-141 is less UV-bright than the other stars, so the stellar absorption of its planet is mostly in the IR. Because of the high UV stellar absorption on HD213885b and HD20329b, their atmospheres become hot enough to emit significant UV radiation.
