The planetary–exoplanetary environment: A nonlinear perspective

A review of the fundamental physical processes in the planetary–exoplanetary environment is presented, with emphasis on nonlinear phenomena. First, we discuss briefly the detection of exoplanets and search for radio emissions from exoplanets. Next, we give an overview of the concepts of waves, instabilities, chaos and turbulence in the planetary–exoplanetary environment based on our present knowledge of the solar-terrestrial environment. We conclude by discussing cyclotron masers and chaos in nonthermal radio emissions in the planetary–exoplanetary environment.
