GJ1214 b Archives

Calculated vertical distribution of abundances for the warm Neptunes GJ 436b and GJ 1214b. The solid lines correspond to the mean abundance, the shaded areas to the range around the mean ±σ, and the dotted lines to the abundances resulting from the unperturbed model. The panels on the left show the effect on the calculated abundances of the uncertainties on (photo)chemical kinetics, while the right panels correspond to the effect on the abundances of the uncertainty in Kzz. -- astro-ph.EP

Quantification Of Abundance Uncertainties In Chemical Models Of Exoplanet Atmospheres

by Keith CowingDecember 4, 2025December 4, 2025

Chemical models are routinely used to predict the atmospheric composition of exoplanets and compare it with the composition retrieved from observations, but little is known about the reliability of the […]

A Photochemical PHO Network For Hydrogen-dominated Exoplanet Atmospheres

by Keith CowingSeptember 13, 2024September 13, 2024

Due to the detection of phosphine PH3 in the Solar System gas giants Jupiter and Saturn, PH3 has long been suggested to be detectable in exosolar substellar atmospheres too. However, […]
