Sub-rotation and Super-rotation in Pulsar Magnetospheres

Abstract

For magnetospheric species that are nonrelativistic at the stellar surface in the general oblique rotator model, it is shown that a ondissipative flow branch which is sub-rotating when near the star remains sub-rotating everywhere, but that one which is super-rotating when near the star can become sub-rotating inside the light cylinder. Hence, both flow branches can cross the light cylinder and remain valid outside it.
