26. Europa plume studies

Lorenz Roth (KTH Royal Institute of Technology, Stockholm, Sweden)

Oral

Outgassing from plumes might enhance the neutral density in Europa’s atmosphere locally and affect the electromagnetic interaction of the moon. In the last seven years, various studies have claimed evidence for plumes erupting from Europa’s surface using a variety of methods from remote-sensing observations from Earth to in-situ plasma measurements. We discuss the studies claiming such plume...

Oral

H2O molecules from Europa's water plumes may be detected by the 2031 flyby of the JUICE mission spacecraft. Previous work on the feasibility of these detections has assumed a collisionless model of the plume particles (Huybrighs et al., 2017). More sophisticated models of the plumes including particle collisions have shown that a shock could develop in the plume interior as rising particles...

27. Multi-fluid MHD Modeling of Europa's Plasma Interaction

Camilla Harris (University of Michigan Ann Arbor)

Oral

Europa hosts a periodically changing plasma interaction driven by the spatial variations of Jupiter's magnetic field and magnetospheric plasma. We have developed a multi-fluid magnetohydrodynamic (MHD) model for the plasma interaction to investigate its response to these magnetic field and plasma variations at Europa's orbit. The model solves the multi-fluid MHD equations for electrons and...

18. Reconnection-driven Dynamics at Ganymede's Upstream Magnetosphere: 3D Global Hall MHD and MHD-EPIC Simulations

Dr Hongyang Zhou (University of Michigan)

Oral

The largest moon in the solar system, Ganymede, is the only moon known to possess a strong intrinsic magnetic field and a corresponding magnetosphere.
Using the latest version of Space Weather Modeling Framework (SWMF), we study the upstream plasma interactions and dynamics in this sub-Alfvenic system.
Results from the Hall MHD and the coupled MHD with embedded Particle-in-Cell (MHD-EPIC)...
