Abstract
The continuous spectra of a 2D inhomogeneous, cylindrical magnetic flu x tube are studied and applied to solar coronal loops. The density is stratified radially as well as longitudinally, while other equilibrium quantities only vary in the radial direction. Stratification causes g aps to appear in the continuous spectrum, and it is shown that discret e global, stratification-induced Alfven eigenmodes occur in these gaps . These global modes may be important for the heating of coronal loops .
