Si. Bastrukov et al., ALFVEN WAVES IN THE ELECTRON-NUCLEAR PLASMA IN THE PERIPHERAL CRUST OF A NEUTRON-STAR AS A RESIDUAL EFFECT OF A SUPERNOVA EXPLOSION, JETP letters, 64(9), 1996, pp. 637-642
The conservation of magnetic flux in the evolution and collapse of mas
sive stars suggests that Alfven magnetoplasma oscillations can be exci
ted in an isolated neutron star by residual (after the supernova explo
sion) disturbances of the magnetized electron-nuclear plasma localized
in the peripheral crust of the star. The frequencies of the poloidal
Alfven oscillations are calculated in the uniform magnetic held approx
imation, and it is found that the periods of the oscillations fall int
o the time interval of the periodicity of radio pulsar radiation. This
coincidence of the periods could mean that, at least for some pulsars
observed in the radio range, the electromagnetic activity is due to c
onverstion of the energy of magnetoplasma oscillations into electromag
netic radiation. (C) 1996 American Institute of Physics.
