Query: Charged dust close to outer mean-motion resonances in the heliosphere   We investigate the dynamics of charged dust close to outer mean-motion
resonances with planet Jupiter. The importance of the interplanetary magnetic
field on the orbital evolution of dust is clearly demonstrated. New dynamical
phenomena are found that do not exist in the classical problem of uncharged
dust. We find changes in the orientation of the orbital planes of dust
particles, an increased amount of chaotic orbital motions, sudden 'jumps' in
the resonant argument, and a decrease in time of temporary capture due to the
Lorentz force. Variations in the orbital planes of dust grain orbits are found
to be related to the angle between the orbital angular momentum and magnetic
axes of the heliospheric field and the rotation rate of the Sun. These
variations are bound using a simplified model derived from the full dynamical
problem using first order averaging theory. It is found that the interplanetary
magnetic field does not affect the capture process, that is still dominated by
the other non-gravitational forces. Our study is based on a dynamical model in
the framework of the inclined circular restricted three-body problem.
Additional forces include solar radiation pressure, solar wind drag, the
Poynting-Robertson effect, and the influence of a Parker spiral type
interplanetary magnetic field model. The analytical estimates are derived on
the basis of Gauss' form of planetary equations of motion. Numerical results
are obtained by simulations of dust grain orbits together with the system of
variational equations. Chaotic regions in phase space are revealed by means of
Fast Lyapunov Chaos Indicators.
