This research explores the Eclipse-Yarkovsky effect's impact on Saturn's ring particles, considering time-dependent changes in solar insolation due to Saturn's orbital eccentricity cycles. The study aims to develop a model for EY-driven ring evolution, quantify angular momentum transport, and assess cumulative effects on ring edges and satellite formation.
Key findings
EY torque on ring particles varies with Saturn's orbital eccentricity, modulating by up to 16% due to solar insolation changes.
Proposed research will develop a time-dependent model for EY-driven ring evolution, incorporating orbital eccentricity cycles.
The study will quantify how different optical depth regimes affect angular momentum transport and assess long-term effects on ring edges and satellite formation.
Limitations & open questions
The research is at the proposal stage and actual observational data or results are not yet available.
The model's accuracy depends on the integration of complex orbital dynamics with thermal torque evolution.
