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...
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...
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)...
