One dimensional simulations of MHD shock heating of a stratified solar coronal hole

Our one dimensional numerical simulations describe the evolution of large amplitude Alfvèn waves excited in the lower corona as they travel upwards guided by the open magnetic field lines of a gravitationally stratified solar coronal hole. When the waves reach the region where β ≪ 1 they develop int...

Zusammenfassung:Our one dimensional numerical simulations describe the evolution of large amplitude Alfvèn waves excited in the lower corona as they travel upwards guided by the open magnetic field lines of a gravitationally stratified solar coronal hole. When the waves reach the region where β ≪ 1 they develop into magnetohydrodynamic (MHD) shocks. The shock waves seem to produce sufficient heat fluxes to be important contributors to the heating of the solar corona.
