Snapshot of the isolated pulsar simulation after 12.4 pulsar spin periods. The central pulsar is represented by a black disk on left panels and a white disk 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 Lorentz factor of the plasma Γ; and the isotropic synchrotron power emitted by the particles per unit of volume $(\text{d}{P}_{\text{rad}}/\text{d}V)(r^2/r_{\star }^2)$. Radii are given in units of the light cylinder radius, represented by the red circle.
