| Abstract: | The motion of electrons and positrons in the vacuum magnetosphere of a neutron star with a surface magnetic field of B ≈ 1012 G is considered. Particles created in the magnetosphere or falling into it from outside are virtually instantaneously accelerated
to Lorentz factors γ ≈ 108. After crossing the force-free surface, where the projection of the electric field onto the magnetic field vanishes, a particle
begins to undergo ultra-relativistic oscillations. The particle experiences a regular drift along the force-free surface simultaneous
with this oscillatory motion. |
