Figure 3

Spatial profile of the charge and current densities together with magnetic field lines at ω _ci t = 6. The magnitude of the charge density ρ = e(N _i   − N _e ) and the magnitudes of current density J _x , J _y , and J _z components are shown by the jet-scale colormap. The magnitude of the charge density is normalized by the initial charge density of solar wind ions eN ₀ , and the magnitude of the current density is normalized by eN ₀ V _s . The results from the low-resolution run (Umeda and Ito 2014) and the high-resolution run are shown in the top and bottom panels, respectively.
