REGIONAL MODELING OF INTERCHANGE STRUCTURES IN THE JOVIAN MAGNETOSPHERE
Seminars
Semester 2
Recent Juno wave data shows distinct signatures of interchange activity within Jupiter’s inner magnetosphere. This process plays a key role in the transport of mass, momentum, and energy in a rotation-dominated environment. However, single-spacecraft measurements are limited by spatio-temporal ambiguities, making it hard to get a comprehensive understanding of evolution. This analysis is further complicated by the flapping of the magnetodisc, driven by Jupiter’s tilted magnetic dipole.
To address these limitations, we have developed a novel magnetohydrodynamics (MHD) code designed for both global and regional Jovian models. By employing advanced numerical methods that ensure strict conservation of angular momentum, the code accurately captures the dynamics of Jupiter’s rapidly rotating magnetosphere. The MHD model also incorporates magnetosphere–ionosphere coupling and mass loading from Io’s volcanic activities, while specifically accounting for Jupiter’s dipole tilt to investigate magnetodisk flapping. This modeling framework will facilitate the interpretation of current observational data and provide predictive insights for future Jovian missions.
