Magnetic Interaction of a Super-CME with the Earth's Magnetosphere: Scenario for Young Earth
2014
Solar eruptions, known as Coronal Mass Ejections (CMEs), are frequently observed on our Sun. Recent Kepler observations of superflares on G-type stars have implied that so called super-CMEs, possessing kinetic energies 10 times of the most powerful CME event ever observed on the Sun, could be produced with a frequency of 1 event per 800-2000 yr on solar-like slowly rotating stars. We have performed a 3D time-dependent global magnetohydrodynamic simulation of the magnetic interaction of such a CME cloud with the Earth's magnetosphere. We calculated the global structure of the perturbed magnetosphere and derive the latitude of the open-closed magnetic field boundary. We also estimated energy fluxes penetrating the Earth's ionosphere and discuss the consequences of energetic particle fluxes on biological systems on early Earth.
