| Zusammenfassung |
| Trajectory and density simulations of interstellar dust particles (ISD)
in the Heliosphere are presented. Relative ISD fluxes are derived
at various locations in the Solar System. Special emphasis is put on
the prediction of densities and fluxes at Cassini orbit. The simulation
results show a fluctuation of the particle density with the Solar Cycle.
The strength and shape of this fluctuation depends on particle surface
optical properties and on the particle charging. Preliminary results
predict the density fluctuations at Saturn orbit to stay in a range
between 0 to 5 times the ISD-density at infinity. The strongest increase
of ISD flux and density is expected at Saturn between 2005 and 2012,
where the peak of the increment differs in time, for different particle
sizes. The simulations can help predicting and reducing the data for
various other interplanetary missions. |
