Spatial profile of the charge and current densities together with magnetic field lines at ω
t = 6. The magnitude of the charge density ρ = e(N
) and the magnitudes of current density J
, and J
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
, and the magnitude of the current density is normalized by eN
. 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.
