Resonant drift echoes in electron phase space density produced by dayside Pc5 waves following a geomagnetic storm
Download2008
Rankin, Robert, Degeling, Alex W.
The interaction between relativistic, equatorially mirroring electrons and Pc5 Ultra Low Frequency (ULF) waves in the magnetosphere is investigated using a numerical MagnetoHydroDynamic (MHD) model for waves and a test-kinetic model for electron phase space density (PSD). The temporal and spatial...

Charged particle behavior in the growth and damping stages of ultralow frequency waves: Theory and Van Allen Probes observations
Download2016
Wygant, John R., Zong, Qui-Gang, Kletzing, Craig A., Blake, J. Bernard, Kivelson, Margaret G., Zhou, Xuzhi, Chen, Xing-Ran, Rankin, Robert, Wang, Zi-Han
Ultralow frequency (ULF) electromagnetic waves in Earth's magnetosphere can accelerate charged particles via a process called drift resonance. In the conventional drift resonance theory, a default assumption is that the wave growth rate is time independent, positive, and extremely small. However,...

A two-dimensional nonlinear multi-fluid MHD model of the ionosperic Alfven resonator is presented. The resonator is excited by a packet of shear Alfven waves propagating downward toward the ionosphere from high altitudes. It is shown that the nonlinear (ponderomotive) force of standing...

Numerical modeling of drift resonance and drift-bounce resonance between ultra-low frequency waves and energetic particles in the inner magnetosphere
DownloadFall 2018
The main topic of this thesis is the investigation of drift resonance and drift-bounce resonance between energetic particles and Pc3-5 Alfvenic ultra-low frequency (ULF) waves in the Earth's inner magnetosphere. We have developed numerical models to simulate how the dynamics of O+, H+ ions and...

Fluxgate magnetometers are an essential tool for solar-terrestrial research and monitoring or forecasting space weather. They provide high precision measurements of the Earth’s magnetic fields and can be used to infer the currents that transport energy and momentum through the magnetosphere and...

Rankin, Robert, Ridley, Aaron J., Gombosi, Tamas I., Clauer, C. Robert, Watanabe, Masakazu, Kabin, Konstantin, Sofko, George J.
On the basis of magnetohydrodynamic simulation results for northward interplanetary magnetic field ( IMF) and significant dipole tilt, we describe internal reconnection processes that occur earthward of the magnetopause subsequent to magnetopause reconnection. We discuss the associated...

Self‐consistent wave‐particle interactions in dispersive scale long‐period field‐line‐resonances
Download2007
Rankin, Robert, Samson, John C., Watt, Clare E. J.
Using 1D Vlasov drift-kinetic computer simulations, it is shown that electron trapping in long period standing shear Alfvén waves (SAWs) provides an efficient energy sink for wave energy that is much more effective than Landau damping. It is also suggested that the plasma environment of low...

Two flybys of Mercury by the NASA MESSENGER spacecraft on January 14 and October 6, 2008 provide insight into the spatial distribution of the heavy ion exosphere around the planet. The relatively quiet solar wind conditions and interplanetary magnetic field (IMF) orientation allow us to compare...
