The shock structure for a perpendicular shock propagating in a quiescent region with n_H= 10⁴ cm⁻³ (left-hand panel) and n_H= 10⁶ cm⁻³ (right-hand panel). From top to bottom panels, we plot the velocity in the x- and z-direction for the neutrals (solid line), ions/electrons (dashed line) and grains (dotted line), the tangential magnetic field and the temperatures of the ions (dashed line), electrons (dotted line) and neutrals (solid line) as well as the absolute value of the grain charge (dash–dotted line). The velocities are normalized with respect to the shock speed and the magnetic field to the total upstream magnetic field.
