Key physico-chemical mechanisms in (exo)planetary atmospheres and their impacts on the observables

Characterizing the atmospheres of extrasolar planets is a new frontier in exoplanetary science, and as such is dependent on observations and interpretation toolkits. A key question in current exoplanetary atmospheric research is what are and how do the key physico-chemical processes determine the atmospheric composition and temperature of exoplanets. In this contribution we review the main mechanisms affecting (exo)planetary atmospheres and some of their impacts on the observables like spectra, composition and temperature. In particular, we focus on atmospheric chemistry under intensive irradiation, and kinetics-related disequilibrium processes in hot/ultra hot Jupiters.
