Abstract

This study presents a fully simulation-based approach to modeling Jupiter’s auroral processes using open-access planetary magnetic field models and Python-based analysis tools. By integrating dipolar magnetic field line tracing, parallel electric field computation, and Poynting flux estimation across a range of ionospheric conductivities and MHD wave parameters, we evaluate the energetics and dynamics of auroral energy transport. The simulation yields peak Poynting flux values (∼67,600 mW/m²) and auroral power outputs (∼2.2 °ø 1021 TW), significantly exceeding values reported by Juno-era observations. Additionally, predicted auroral brightness (∼1022 Rayleighs) and unphysical AlfvÅLen speeds (∼8.9 °ø 10⁶ km/s) suggest overestimations stemming from assumptions in plasma density and field alignment. The absence of modeled precipitating electron flux further contrasts with typical magnetosphere-ionosphere coupling observations. Despite these discrepancies, the model captures the system’s high sensitivity to Pedersen conductance and Alfv'enic turbulence, supporting theoretical predictions of nonlinear feedback in auroral generation. This work demonstrates both the potential and the limitations of accessible, code-based planetary simulations in replicating outer planetary magnetospheric phenomena, and sets the stage for future studies with realistic wave-particle interactions and validated input parameters.
