Propagation of Long-Wavelength Nonlinear Slow Sausage Waves in Stratified Magnetic Flux Tubes
The propagation of nonlinear, long-wavelength, slow sausage waves in an expanding
magnetic flux tube, embedded in a non-magnetic stratified environment, is discussed.
The governing equation for surface waves, which is akin to the Leibovich–Roberts
equation, is derived using the method of multiple scales. The solitary wave solution of the
equation is obtained numerically. The results obtained are illustrative of a solitary wave
whose properties are highly dependent on the degree of stratification
