Density maps for electrons, positrons, and protons (left to right), for f_pp = 0.01, f_pp = 0.05 and f_pp = 0.1 (top to bottom), as a function of r/R_LC and θ, for t = 5P. The densities are normalised by , where is the polar GJ number density. Solid black lines are the magnetic field lines. The dashed black line indicates the distance from the rotation axis r sin θ = R_LC and the grey semi-disc represents the neutron star. The densities are in log scale in order to enhance the contrast.
