Thermal Inversion

A layer in which temperature rises with altitude rather than falling, created when high-altitude absorbers soak up starlight — the exoplanet analogue of Earth's ozone stratosphere. On the hottest giant planets, absorbers such as titanium oxide or metals can drive inversions, which flip molecular features in an emission spectrum from absorption to emission.

Highlights

  • Temperature rising with altitude — flips emission features
