Mapping the atmospheres and surfaces of exoplanets is ailed by degeneracies due to the choice of map structure and orbital parameter uncertainties. Today’s paper attempts to solve this by using a principal component analysis approach.
Scrutinizing a popular method of characterizing exoplanet atmospheres reveals an inherent degeneracy that may only be overcome in special cases.
Cues from stellar atmospheric chemistry can help in explaining the observations of very-hot gas giant atmospheres.
The hottest point in hot Jupiter atmospheres should be directly below their star or blown slightly eastward by winds. What is happening on CoRoT-2b?
Planets that do not transit are very difficult for Kepler to find. The authors of today’s paper are not intimidated by that and find 60 non-transiting Hot Jupiters unknowingly detected by Kepler anyway.
If you thought the weather on Earth was wild, think again: today we’re discussing the climate of WASP-121b.
