# Three-dimensional Propagation of Magnetohydrodynamic Waves in Solar Coronal Arcades

@article{Rial2010ThreedimensionalPO, title={Three-dimensional Propagation of Magnetohydrodynamic Waves in Solar Coronal Arcades}, author={S. Rial and I. Arregui and Jaume Terradas and Ram{\'o}n Oliver and Jos{\'e} Luis Ballester}, journal={The Astrophysical Journal}, year={2010}, volume={713}, pages={651-661} }

We numerically investigate the excitation and temporal evolution of oscillations in a two-dimensional coronal arcade by including the three-dimensional propagation of perturbations. The time evolution of impulsively generated perturbations is studied by solving the linear, ideal magnetohydrodynamic (MHD) equations in the zero-β approximation. As we neglect gas pressure, the slow mode is absent and therefore only coupled fast MHD and Alfven modes remain. Two types of numerical experiments are… Expand
