The solar sources of magnetic helicity in interplanetary space
Abstract
About one third of all coronal mass ejections (CMEs) in the solar wind possess the internal structure of helical magnetic flux ropes. Recent studies have shown that the magnetic chiralities of the flux ropes can be traced back to individual bipolar regions in the Sun's northern and southern hemispheres. This presentations presents an overview about the solar source regions that lead to helical flux rope CMEs in the interplanetary medium including their solar cycle variability and addresses the possibility of conservation of magnetic helicity in space plasmas.
