Absorption of Magnetosonic Waves in the Crust of Neutron Stars. Radio Emission from Pulsars
The kinetic equation for plasma in the crust of neutron star is solved in the relaxation time approximation. Values of the kinetic coefficients are obtained for crust plasma? with densities in the range of 10 2 - 10 14 g/cm 3 . The propagation of magnetosonic waves in the crust of neutron star is ex...

. The propagation of magnetosonic waves in the crust of neutron star is examined with various mechanisms for the dissipation of the wave energy taken into account. It is shown that the crust of neutron star are transparent for magnetosonic waves with frequencies ω ≤ 10
11
Hz and that the wave absorption is lower for stars with higher central densities. A mechanism for radio emission by pulsars is proposed in which the source is on the star’s surface and has dimensions equal to the cross section of the beam of magnetosonic waves. Some features of the radio emission (spectral index and pulsar cutoff) are explained. |
