Alfvenic fronts and the turning-off of the energy release in solar flares
Abstract
The effect of impulsively turning off the dissipation in an existing model for energy propagation through Alfvenic fronts into the coronal site of enerrgy release in a solar flare is examined. In the optimum case of impedance matching, the flux tube re-stresses on a much longer timescale than it relaxes, suggesting an explanation for the timescales observed in homologous flares.
