Global plasma and magnetic structures forming in a pulsar magnetosphere of magnetic obliquity χ = 30°. Left panel: Three-dimensional rendering of the plasma density (color-coded) normalized by the surface Goldreich-Julian density and multiplied by (r/r_⋆)² to compensate for the effect of expansion. Closed and open field lines encompassing the equatorial current layer are shown by blue lines. The star is the gray sphere in the center. Right panels: Poloidal (top, y = 0) and toroidal (bottom, z = 0 or θ = 90°) slice of the plasma density. The light cylinder is shown with the white dashed line. The dotted lines represent the split-monopole solution, and the magenta arrow shows the orientation of the magnetic moment of the star at this time.
