On the Axisymmetric Force-free Pulsar Magnetosphere
We investigate the axisymmetric magnetosphere of an aligned rotating magnetic dipole surrounded by an ideal force-free plasma. We concentrate on the magnetic field structure around the point of intersection of the separatrix between the openand closed-field line regions and the equatorial plane. We first study the case in which this intersection point is located at the light cylinder. We find t...
متن کاملOn the self-consistent model of the axisymmetric radio pulsar magnetosphere
We consider a model of axisymmetric neutron star magnetosphere. In our approach, the current density in the region of open field lines is constant and the returning current flows in a narrow layer along the separatrix. In this case, the stream equation describing the magnetic field structure is linear both in the open and closed regions, the main problem lying in matching the solutions along th...
متن کاملSome Properties of an Axisymmetric Pulsar Magnetosphere Constructed by Numerical Calculation
We have explored the magnetosphere described by a numerical solution for an axisymmetric rotating field satisfying the force-free and ideal MHD conditions everywhere. The electric current distribution is determined by the requirement of continuity and smoothness of the flux function across the light cylinder. The overall magnetic field structure is obtained using the numerical result. We also c...
متن کاملPolarization transfer in pulsar magnetosphere
Propagation of radio waves in the ultrarelativistic magnetized electronpositron plasma of pulsar magnetosphere is considered. Polarization state of the original natural waves is found to vary markedly on account of the wave mode coupling and cyclotron absorption. The change is most pronounced when the regions of mode coupling and cyclotron resonance approximately coincide. In cases when the wav...
متن کاملThe Disturbance of a Millisecond Pulsar Magnetosphere
Pulsar timing has enabled some of the strongest tests of fundamental physics. Central to the technique is the assumption that the detected radio pulses can be used to accurately measure the rotation of the pulsar. Here we report on a broad-band variation in the pulse profile of the millisecond pulsar J1643−1224. A new component of emission suddenly appears in the pulse profile, decays over 4 mo...
