Fig. 4


Top panel: dispersion curves of an unstable kink (m = 1) mode propagating on a moving twisted magnetic flux tube with twist parameter ε = 0.025 at η = 0.88, b = 1.58 and Alfvén Mach numbers equal to 2.95, 2.975, 3, and 3.025. Bottom panel: growth rates of the unstable kink mode. Note that the marginal red curve reaches values lower than 0.001 beyond kza = 53.
