Dust motion in Jupiter's tilted magnetic field

摘要: Abstract We outline an analytical method for studying the motion of charged dust particles that orbit oblate planet having a tilted, offset, dipolar magnetic field. Our computed trajectories closely mimic previous numerical results; equilibrium potentials must be less then 10 volts or Jovian ring would thicker than observed. identify several Lorentz resonances , where periods components force, as seen by reference particle moving in equatorial plane, match particle's orbital period; seem to near observed features system.
