Time-Varying Magnetopause Reconnection during Sudden Commencement: Global MHD Simulations
J. W. B. Eggington, R. T. Desai, L. Mejnertsen +2
In response to a solar wind dynamic pressure enhancement, the compression of the magnetosphere generates strong ionospheric signatures and a sharp variation in the ground magnetic…
Drift Orbit Bifurcations and Cross-field Transport in the Outer Radiation Belt: Global MHD and Integrated Test-Particle Simulations
R. T. Desai, J. P. Eastwood, R. B. Horne +10
Energetic particle fluxes in the outer magnetosphere present a significant challenge to modelling efforts as they can vary by orders of magnitude in response to solar wind driving…
Interplanetary Shock-induced Magnetopause Motion: Comparison between Theory and Global Magnetohydrodynamic Simulations
Ravindra T. Desai, Mervyn P. Freeman, Jonathan P. Eastwood +10
The magnetopause marks the outer edge of the Earth's magnetosphere and a distinct boundary between solar wind and magnetospheric plasma populations. In this letter, we use global m…
Photodetachment and Test-Particle Simulation Constraints on Negative Ions in Solar System Plasmas
Ravindra T. Desai, Zeqi Zhang, Xinni Wu +1
Negative ions have been detected in abundance in recent years by spacecraft across the solar system. These detections were, however, made by instruments not designed for this purpo…
Particle-In-Cell Simulations of the Cassini Spacecraft's Interaction with Saturn's Ionosphere during the Grand Finale
Zeqi Zhang, Ravindra T. Desai, Yohei Miyake +2
A surprising and unexpected phenomenon observed during Cassini's Grand Finale was the spacecraft charging to positive potentials in Saturn's ionosphere. Here, the ionospheric plasm…
Three Dimensional Simulations of Solar Wind Preconditioning and the 23 July 2012 Interplanetary Coronal Mass Ejection
Ravindra T. Desai, Han Zhang, Emma E. Davies +3
Predicting the large-scale eruptions from the solar corona and their propagation through interplanetary space remains an outstanding challenge in solar- and helio-physics research.…
