| Abstract : | Gravito-electrodynamic forces play a significant role in the dynamics of highly charged dust particles in Saturn's D68 ringlet. Our Numerical analysis reveals that stable particles follow circular paths around the planet, transitioning from one magnetic field line to the next, while those moving towards or away from the planet move in a bouncing pattern up and down the equatorial plane reaching the planet or adjacent ringlet or rings at different longitudes and time interval. Particles launched at Keplerian speeds with sizes between 1e-11m and 2.1e-11m are stable, sizes between 2.2e-11m and 9.7e-11m move towards the planet, impacting it at various longitudes and time intervals, while particles between 9.8e-10m and one nanometer move away from the planet. Particles launched at clumps' speeds exhibit similar behavior to Keplerian launch particles. Those with sizes ranging from 9.5e-11m to one nanometer move away, while particles between 0.94e-10m and 0.22e-10m reach the planet's atmosphere at the equator. Particles in the size range of 0.1e-10m to 0.21e-10m move in stable circular paths along magnetic field lines around Saturn. Particles launched at the planet's rotational speed, with sizes between 0.1e-10m and 0.28e-10m, exhibit stability. However, those between 0.29e-10m and 9 nanometers, as well as 30 nanometers to the microscale, move towards the planet and eventually reach its equatorial atmosphere. Particles sized between 10 nanometers and 30 nanometers move away from the planet. Particles moving away from the planet are anticipated to be recaptured by the D or C rings, contributing to the recycling of ring materials within the equatorial plane. Conversely, particles moving toward the planet are likely to be the source of falling material observed during Cassini's missions, supporting the hypothesis that these particles originate from the D68 ringlet. |
