Alfvén Waves and the Heating of Solar Coronal Loops
Abstract
We construct a 3D magnetic model for the dissipation and propagation of Alfvén waves in a coronal loop. The waves are assumed to be generated by foot-point motions inside the kilogauss magnetic flux elements at the two ends of the loop. Counter propagating waves are subject to non-linear interactions that lead to turbulent decay of the waves and heating of the chromospheric and coronal plasma. We find that hot coronal loops typically found in active region and the underlying chromosphere can be explained by Alfvén wave turbulence.
