Exploring hot mini-neptune atmospheres

Motivated by the diversity of exoplanets detected by ground and space surveys, we use a one-dimensional photochemical model that includes disequilibrium chemistry to build a grid of hot extrasolar giant and mini-Neptune atmospheres around F, G, K and M stars. We address the differences in hot exoplanet atmospheres according to the observables semi-major axis and stellar type, exploring their detectable atmospheric features. These planets are interesting targets for future observations, therefore, addressing their atmospheric structure and composition is a major issue and the aim of our work. Our atmospheric grid can be applied to current and future planetary observations to characterize exoplanet atmospheres and serves as a reference to interpret the results of atmospheric retrieval analysis.
