Based on double-adiabatic formulation, the normalized phase speed is plotted as a function of propagation angle in the polar coordinate plane. The parameters used are (a) , , (b) , , (c) , and (d) , . The black line represents the phase speed of fast mode, red line represents speed of Alfvén mode and blue line represents speed of slow mode.
Formation of reconnection layer in the outflow region of magnetic reconnection in the plane. The reconnection layer consists of several discontinuities/shocks, which emanate from the point . For illustration purpose, two discontinuities and are plotted.
Magnetic hodograms in plane for the six simulation cases shown in Fig. 3: (a) SS-RD (DD) compound structure with and , (b) SS-RD (DD) compound structure with and , (c) SS-RD-SS compound structure with and , (d) SSS with and , (e) SS-RD-SS compound structure with and , and (f) RD-SS compound structure with and .
The type of compound structure depends on initial ion beta and magnetic shear angle . The distribution of compound structures, RD-SS, SS-RD-SS, SS-RD and SSS, is plotted in plane.
