Fig. 5.From: Ballooning modes and their stability in a near-Earth plasmaDependence of the discrete spectrum Ω2 = (ωL/Va0)2 on parameter β0 under k y a = 2 (left-hand panel), and the same dependence, but on k y under β0 = 0.95 (right-hand panel). The parameters P∞/P0 = 1, a/r0 = 1/6, and v = 0.5. The numbers of radial harmonics are shown near curves.Back to article page
