The general dispersion relation for the vibration modes of magnetic flux tubes
Abstract
The general dispersion relation for wave modes in a magnetic flux tube embedded in a compressible but unstratified atmosphere is obtained and is solved numerically for several different sets of atmospheric parameters. Approximate analytic solutions for the phase velocity are also recovered in the thin tube approximation and these are compared with the numerical solutions. The nature of the different modes is discussed and particular attention is given to the interface or long wavelength mode, and to the 'taut wire' mode.
