Exploring the Chemistry of Sub-Neptune Atmospheres
This chapter examines the atmospheric chemistry of sub-Neptune planets, focusing on chemical equilibrium, quenching processes, and the influence of extreme temperatures and pressures on molecular reactions. It highlights the implications of nitrogen depletion and the role of silicate melts as nitrogen sinks, alongside comparisons with Earth's geological processes. Advanced observations, particularly from the James Webb Space Telescope, offer insights into the unique characteristics and potential biosignatures of exoplanets like TOI-270d and K2-18b.
