Exoplanet atmospheres: A theoretical outlook [PDF]
Proceedings of the International Astronomical Union, 2010 AbstractWith over two dozen exoplanet atmospheres observed today, the field of exoplanet atmospheres is solidly established. The highlights of exoplanet atmosphere studies include: detection of molecular spectral features; constraints on atmospheric vertical temperature structure; detection of day-night temperature gradients; and a new numerical ...

Exoplanet Aeronomy: A Case Study of WASP-69 b’s Variable Thermosphere
The Astronomical JournalAeronomy, the study of Earth’s upper atmosphere and its interaction with the local space environment, has long traced changes in the thermospheres of Earth and other solar system planets to solar variability in the X-ray and extreme-ultraviolet ...

A Photochemical Phosphorus-Hydrogen-Oxygen Network for Hydrogen-dominated Exoplanet Atmospheres
The Astrophysical JournalDue to the detection of phosphine (PH _3 ) in the solar system gas giants Jupiter and Saturn, PH _3 has long been suggested to be detectable in exosolar substellar atmospheres too.

JWST/NIRISS Reveals the Water-rich “Steam World” Atmosphere of GJ 9827 d
The Astrophysical Journal LettersWith sizable volatile envelopes but smaller radii than the solar system ice giants, sub-Neptunes have been revealed as one of the most common types of planet in the galaxy. While the spectroscopic characterization of larger sub-Neptunes (2.5–4 R _⊕ ) has

The Astrophysical Journal LettersThe recent discovery of “ultrahot” ( P < 1 day) Neptunes has come as a surprise: some of these planets have managed to retain gaseous envelopes despite being close enough to their host stars to trigger strong photoevaporation and/or Roche lobe overflow ...
