Venus As An Exoplanet: I. An Initial Exploration Of The 3-D Energy Balance For A CO2 Exoplanetary Atmosphere Around An M-Dwarf Star
The chemical evolution of an exoplanetary Venus-like atmosphere is dependent upon the ultraviolet to near ultraviolet (FUV-NUV) radiation ratio from the parent star, the balance between CO2 photolysis and recombination […]
