Kinetic and Photochemical Disequilibrium in the Potentially Carbon-rich Atmosphere of the Warm Jupiter WASP-69 b

Kinetic and Photochemical Disequilibrium in the Potentially Carbon-rich Atmosphere of the Warm Jupiter WASP-69 b

High-resolution transmission spectroscopy of the warm gas giant WASP-69 b has revealed the presence of H _2 O, CO, CH _4 , NH _3 , and C _2 H _2 in its atmosphere. This study investigates the impact of vertical diffusion and photochemistry on its atmospheric composition, with a focus on the detected...
