55 Cnc e Temperature

Climate of lava planets

Mark Hammond and Ray Pierrehumbert are studying the atmospheric dynamics of lava planets. Lava planets are rocky planets which are so hot that they have a permanent dayside magma ocean. Their first paper on the planet 55 Cancri-e is here.


Ammonia on Jupiter, Hydrogen Sulfide on Uranus

Pat Irwin's group, which is active in characterization of Solar System planetary atmospheres as well as exoplanet atmospheres. has characterized the distribution of ammonia in the atmosphere of Jupiter (see their paper here) and hydrogen sulfide in the atmosphere of Uranus (paper here, some news coverage here and here).
