Magnetic Helicity and Coronal Mass Ejections View all abstracts by submitter

Alexander Nindos   Submitted: 2005-11-02 03:52

Magnetic helicity is a quantity that descibes the chiral properties ofmagnetic structures. It has the unique feature that it is probably theonly physical quantity which is approximately conserved even inresistive MHD. This makes magnetic helicity an ideal tool for theexploration of the physics of coronal mass ejections (CMEs). CMEscarry away from the Sun twisted magnetic fields and the concept ofhelicity can be used to monitor the whole history of a CME event fromthe emergence of twisted magnetic flux from the convective zone to theeruption and propagation of the CME into interplanetary space. Idiscuss the sources of the helicity shed by CMEs and the role ofmagnetic helicity in the initiation of CMEs.
