Poyting flux luminosity of solutions with realistic pair formation in units of ﹩{{L}_{0}}={{\mu }^{2}}{\Omega }_{*}^{4}/{{c}^{3}}﹩ as a function of the inclination angle (red triangles), measured at the stellar surface. The error bars correspond to the dissipated fraction of the Poynting flux within 2R_LC. Blue points show the results of PIC simulations with abundant pair formation (Section 3), and the blue curve shows the prediction of the MHD model.
