On magnetic-field-induced corrections to the orbital and epicyclic frequencies: paper II. Slowly rotating magnetized neutron stars

Popis výsledku v původním jazyce

We study non-geodesic corrections to the quasicircular motion of charged test particles in the field of magnetized slowly rotating neutron stars. The gravitational field is approximated by the Lense-Thirring geometry, and the magnetic field is of the standard dipole character. Using a fully relativistic approach, we determine the influence of the electromagnetic interaction (both attractive and repulsive) on the quasicircular motion. We focus on the behaviour of the orbital and epicyclic frequencies ofthe motion. Components of the four-velocity of the orbiting charged test particles are obtained by the numerical solution of equations of motion, and the epicyclic frequencies are obtained by using the standard perturbative method. The role of the combined effect of the neutron star magnetic field and its rotation in the character of the orbital and epicyclic frequencies is discussed. It is demonstrated that even in the Lense-Thirring spacetime, particles being static relative to distant
