Mimicking neutron star precession by polar cap current-pattern drifting
We propose a model for rotating current patterns within radiopulsar polar cap accelerators which has observational consequences that mimic those which have been attributed to neutron star precession. The model is a simple extension of a commonly used one for the origin of the ”drifting subpulses” often observed within the pulse envelope of radiopulsars. The new model’s current pattern rotation ...
متن کاملDo superfluid instabilities prevent neutron star precession?
We discuss short wavelength (inertial wave) instabilities present in the standard twofluid neutron star model when there is sufficient relative flow along the superfluid neutron vortex array. We demonstrate that these instabilities may be triggered in precessing neutron stars, since the angular velocity vectors of the neutron and proton fluids are misaligned during precession. The presence of s...
متن کاملRadiative Precession of an Isolated Neutron Star
Euler’s equations of motion are derived exactly for a rigid, triaxial, internally frictionless neutron star spinning down electromagnetically in vacuo. It is shown that the star precesses, but not freely: its regular precession relative to the principal axes of inertia couples to the component of the radiation torque associated with the near-zone radiation fields and is modified into an anharmo...
متن کاملVelocity of auroral arcs drifting equatorward from the polar cap
The drift velocity of an auroral arc is compared with the component of F-region plasma velocity in the same direction for ten cases where the arc is seen to move steadily equatorward for several minutes without any major change in appearance or orientation. In most cases the two velocities are close, but on two occasions the drift velocity of the arc is much higher than the plasma velocity. Fro...
متن کاملIncompatibility of long-period neutron star precession with creeping neutron vortices
Aims. To determine whether “vortex creep” in neutron stars, the slow motion of neutron vortices with respect to pinning sites in the core or inner crust, is consistent with observations of long-period precession. Methods. Using the concept of vortex drag, I discuss the precession dynamics of a star with imperfectly-pinned (i.e., “creeping”) vortices. Results. The precession frequency is far too...
