Modeling Kelvin–Helmholtz Instability in Soft X-Ray Solar Jets

Figure 3

(a) Dispersion curves of stable and unstable kink () MHD mode propagating in a moving untwisted magnetic flux tube of incompressible plasma surrounded by cool medium at the same input parameters as in Figure 2. The dispersion curves of unstable modes located above the middle of the plot have been calculated for , 4.01, 4.035, and 4.06. Alfvén Mach numbers associated with the nonlabeled black, green, and purple curves are equal to 3.796, 3.815, and 3.83, respectively, while those of far right green and purple semiclosed curves have magnitudes of 3.925 and 3.965. (b) Similar plots as in Figure 2.
