The solar atmosphere, acting as a nonlinear dissipative system subjected to an external forcing (i.e. non-zero energy flow), presents a state of reduced symmetry with the consequent formation of convective and magnetic structures and evolution of associated patterns. These magneto-convective structures, modulated by the global dynamo, interact with the hosted planets and impact the climate and habitability of terrestrial (exo)planets. Innovative spectral proxies of solar activity and planetary climatic response may be useful for application to observational surveys of UV activity in Sun-like stars and IR signal in exoplanetary systems.
