Coronal oscillations
Abstract
The detection of coronal waves provides us with a new tool for the determination of the unknown parameters of the corona - MHD seismology of the corona. The method is similar to helioseismology. But MHD coronal seismology is much richer as it is based upon three different wave modes - Alfvén, slow and fast magnetoacoustic modes. These MHD modes have quite different dispersive, polarization and propagation properties, which make this approach even more powerful. The delicate interplay of MHD wave theory and the observations of coronal waves and oscillations are presented, illustrating it with several examples.
