Full Metal Sky
What do the atmospheres of ultra-hot Jupiters and 70s music have in common? A good deal of metal.
More Informative Mapping of Exoplanetary Peekaboos
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.
Blurred Lines: degeneracies in modeling exoplanet atmospheres
Scrutinizing a popular method of characterizing exoplanet atmospheres reveals an inherent degeneracy that may only be overcome in special cases.
An Occam’s razor for very-hot hot Jupiters
Cues from stellar atmospheric chemistry can help in explaining the observations of very-hot gas giant atmospheres.
Blowing the wrong way round? Westward winds on CoRoT-2b
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?
Teaching Computers to Find Non-Transiting Hot Jupiters
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.
