Snapshot of the D9R1 run after 11.7 pulsar spin periods. The central pulsar and the companion (of distance d_comp = 9R_LC and size r_comp = r_⋆) are represented by black disks on left panels and white disks on right panels, for better visualization purposes. From top left to bottom right: toroidal magnetic field $(B_{\varphi }/B_{\star })(R_{\text{LC}}r/r_{\star }^2)$, where solid lines are the magnetic field lines; the mean Lorentz factor of particles, ⟨γ⟩; the bulk velocity of the wind, Γ; the isotropic synchrotron power emitted by the particles per volume unit $(\text{d}{P}_{\text{rad}}/\text{d}V)(r^2/r_{\star }^2)$. Radii are given in units of the light cylinder radius, represented by the red circle. The white dashed lines indicate the aperture angle of the shocked zone appearing on panel (c); we report them in panel (d) for comparison with the emitting hollow cone.
