Coronal Heating and Turbulence from Drift-Alfven Structures by Current Loops and Instabilities

Theory and simulations are used to investigate the Drift-Alfven waves and coherent structures launched by flux tube loops of various heights/diameters and collisionality regimes from the photosphere through the transition layer and into the corona. Collisional terms, electron inertia dispersion and ion polarization currents are included in the dynamical equations. Energy densities and Alfvenic Poynting fluxes are evaluated. The coherent interaction between a large number of neighboring current loops is studied and the reconnection rate reported. We attempt to estimate many hours it takes for a set of neighboring flux tubes to reconnect and estimate the fractions of the released magnetic energy that goes into plasma flows, plasma heating and radiation.
