What do the atmospheres of ultra-hot Jupiters and 70s music have in common? A good deal of metal.
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.
We dive back into one of the earliest studies of the outer solar system that helped us understand how four gas giants playing a chaotic game of catch could have knocked Pluto into its topsy-turvy orbit.
Cues from stellar atmospheric chemistry can help in explaining the observations of very-hot gas giant atmospheres.
