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

A Novel Approach to Resonant Absorption of the Fast MHD Eigenmodes of a Coronal Arcade
The arched eld lines forming coronal arcades are often observed to undulate as magne- tohydrodynamic (MHD) waves propagate both across and along the magnetic eld. These waves are most likely aExpand
