A unique hot Jupiter spectral sequence with evidence for compositional diversity
The emergent spectra of close-in, giant exoplanets ('hot Jupiters') are expected to be distinct
from those of self-luminous objects with similar effective temperatures because hot Jupiters …

Beyond equilibrium temperature: how the atmosphere/interior connection affects the onset of methane, ammonia, and clouds in warm transiting giant planets
The atmospheric pressure–temperature profiles for transiting giant planets cross a range of
chemical transitions. Here we show that the particular shapes of these irradiated profiles for …
