The impact of lightning on the atmospheric composition of an exoplanet in the Habitable Zone

New telescopic measurements are beginning to provide tantalising glimpses into the chemical composition of exoplanetary atmospheres. We use a global 3-D model of atmospheric physics and chemistry to understand variations in observed spectral-resolved measurements in terms of physical and chemical processes. We will study the stability of chemical regimes against perturbations from stellar flares and lightning and examine how these perturbations will influence telescopic measurements of exoplanetary atmospheres. Understanding these variations driven by physical and chemical processes has implications for studying biosignature candidates.
