内容記述 | The motion of ultrarelativistic ions in an oblique magnetosonic shock wave is studied analytically and numerically. The zeroth-order theory predicts that an oblique shock wave can accelerate ions in the direction nearly parallel to the magnetic field if the shock speed is vsh ? c?cos?θ, where θ is the angle between the wave normal and the magnetic field, while the perturbation is a one-dimensional oscillation nearly perpendicular to the zeroth-order motion. The perturbation frequency ω is of the order of Ωi0γ?1/2, where γ is the Lorentz factor of the zeroth-order velocity. These theoretical predictions are examined with test particle simulations, in which the test particle orbits are calculated with use of the electromagnetic fields of a shock wave obtained from an electromagnetic particle simulation. The zeroth-order and perturbed motions in the simulations are explained by the theory. | |||||
