Current Helicity in Response to Coronal Mass Ejections

Coronal mass ejections (CMEs), powerful solar eruptions with massive plasma ejected into the interplanetary space, are caused by the release of the magnetic free energy stored in coronal electric currents. Photospheric current helicity, defined as the integral of the product of the vertical electric...
