Title: Shock Formation and Wind Energetics of Solar Coronal Plumes
Abstract: We investigate the shock formation and wind energetics of solar coronal plumes. Our models consider the effects of slow magnetosonic waves with the wave parameters given by recent observations (mostly SOHO/UVCS). Our models take into account newly derived spreading functions of the plumes. We find that the heating of the plumes by the waves is highly influenced by the carry-along effect of the wind, particularly for long-period waves. Slow magnetosonic waves significantly contribute to the plume energy input, even though other mechanisms as e.g. Alfven waves are expected to dominate at large coronal heights.
