The exotic weather of the hot Jupiter WASP-121 b
Max Planck Institute for Astronomy, Heidelberg
SummaryThrough observations of the exoplanet WASP-121 b with the Hubble Space Telescope, we have studied the atmospheric conditions on the night side of a hot Jupiter in detail for the first time. Incorporating measurements from the dayside, we determined the temperature profile in the stratosphere and an unusual water cycle between the two hemispheres. This study is a significant step towards deciphering the global matter and energy cycles in the atmospheres of exoplanets.
