ABSTRACT

The equations of magnetohydrodynamics are used here to show that the energy released at the inner surface of the crust of a neutron star generates magnetosonic wave beams that propagate to the star’s surface. These equations can be linearized under the conditions of matter in the crust of neutron stars and for frequencies and they are solved here. A standing wave beam with a constant radius develops in the crust. The outer base of this beam on the star’s surface is a source of radio emission. Electrical currents are excited in this source and it becomes an antenna that emits radio waves into the circumstellar space. The intensity of the radio emission decreases at higher frequencies, so that the spectrum of pulsars is bounded above (ω ≤ 1011). More... »
