Kelvin‐Helmholtz unstable magnetotail flow channels: Deceleration and radiation of MHD waves
Download2014
Turkakin, Hava, Rankin, Robert, Mann, Ian R.
The Kelvin-Helmholtz instability (KHI) of magnetotail flow channels associated with bursty bulk flows (BBFs) is investigated. MHD oscillations of the channel in both kink and sausage modes are investigated for KHI, and both the primary and secondary KHIs are found that drive MHD waves. These...

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,...

Dynamic response of Earth's magnetosphere to By reversalsournal of Geophysical Research: Space Physics, 108(A3), [pp

Papitashvili, V., Clauer, C. Robert, Kabin, Konstantin, Gombosi, Tamas I., DeZeeuw, Darren L., Rankin, Robert, Marchand, Richard, Ridley, Aaron J.
In this paper we use a three-dimensional magnetohydrodynamic (MHD) model to study the response of the magnetosphere-ionosphere system to a sudden change in the sign of the By component of the interplanetary magnetic field. We find that after such a change the magnetosphere responds as a linear...

Shear Alfvén waves on stretched magnetic field lines near midnight in Earth's magnetosphere
Download2000
Tikhonchuk, Vladimir T., Rankin, Robert, Fenrich, Frances
The spectrum of toroidal standing shear Alfvén waves (SAWs) is derived for a stretched magnetic field line geometry that is approximated by the Tsyganenko 96 magnetic field model. The model is applied to field lines near the midnight meridional plane. It is demonstrated that the fundamental mode...

Open‐closed field line boundary position: A parametric study using an MHD modelournal of Geophysical Research: Space Physics, 109(A5), [pp

De Zeeuw, Darren L., Clauer, C. Robert, Kabin, Konstantin, Gombosi, Tamas I., Rostoker, Gordon, Rankin, Robert, Rae, I. Johnathan, Marchand, Richard, Ridley, Aaron J.
In this paper we investigate the effect of changes in the interplanetary magnetic field ( IMF), solar wind dynamic pressure, and dipole tilt angle on the position of the ionospheric projection of the open-closed field line boundary (OCB) in a magnetohydrodynamic (MHD) model. We carry out a large...

Tikhonchuk, V. T., Voronkov, I., Samson, J. C., Rankin, Robert
A model is presented that describes the excitation of density perturbations and parallel electric fields by standing shear Alfven waves on dipole fields in Earth's magnetosphere. The model includes the effects of electron inertia and gyro-kinetic dispersion, accounting for field-aligned...

Diffraction, self‐focusing, and the geometrical optics limit in laser produced plasmas
1987
Capjack, C. E., Birnboim, A., Rankin, Robert, Marchand, Richard
The effect of diffraction on the self‐modulation of an intense laser beam in an initially uniform hydrogen plasma is investigated. A formalism is used in which the diffraction term in the paraxial wave equation can be arbitrarily reduced by the use of a weight factor ι. In the limit where ι...

Kabin, Konstantin, Rankin, Robert, Sydorenko, Dmytro
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...

Electrodynamics of magnetosphere‐ionosphere coupling and feedback on magnetospheric field line resonances
Download2007
Marchand, Richard, Lu, J. Y., Rankin, Robert, Solomon, Stanley C., Wang, Wenbin, Lei, J., Rae, I. Johnathan
We present a new dynamic model that describes coupling between standing inertial or ion-acoustic-gyroradius-scale shear Alfven waves, compressional modes, and auroral density disturbances. The model is applied to the excitation of field line resonances (FLRs) in dipolar and stretched geomagnetic...
