![Top left: (pgas, Tgas) cross-section through the terminators of WASP-69 b, with the location of the CH4 quench point overlaid (light blue line). We define the CH4 quench level as the pressure where the absolute relative difference between the equilibrium and disequilibrium concentrations first exceeds 10−3. Top right: Column densities in the line-of-sight direction in the atmosphere of WASP-69 b for [M/H] = 1.0, and C/O = 0.55 for CH44. Bottom: The same as for CH4 but now for SO2 (left) and CO2 (right). The terminator pressure scale is used as a radius axis. The hotspot offset at 10−4 bars is reflected in the column density of SO2, with larger concentrations being formed on the evening terminator. -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/08/Chemical-Tracers.png?resize=1200%2C716&ssl=1)
[astro-ph.EP] Warm giant exoplanets exhibit strong three-dimensional temperature contrasts that can significantly alter atmospheric chemistry through quenching and photochemistry, yet transmission spectra are commonly interpreted using one-dimensional, limb-averaged models. Such […]

A Combined 3D Model Applied To Cloudy Warm Saturn Type Exoplanets Around M-dwarfs
Warm Saturn type exoplanets orbiting M-dwarfs are particularly suitable for in-depth cloud characterisation through transmission spectroscopy due to their favourable stellar to planetary radius contrast.
