Interaction of ULF waves with different ion species: Pitch angle and phase space density implications
Download2016
Ren, Jie, Zong, Qui-Gang, Rankin, Robert, Zhou, Xuzhi, Wang, Y. F.
ULF waves can accelerate/decelerate the charged particles including the ring current ions via drift-bounce resonance, which play an important role in the dynamics of ring current during storm times. This study compares the different behaviors of oxygen ions (10.5–35.1 keV) and protons (0.3–12.3...

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...

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...

Kinetic theory of stimulated Raman sidescattering from magnetized plasmas
1985
Boyd, T. J. M., Rankin, Robert
A theory of stimulated Raman sidescattering in magnetized plasmas is presented based on a solution of the Vlasov–Maxwell equations. The incident laser light, in the form of extraordinary mode radiation, decays into light waves which propagate along the uniform magnetic field as right or left...

Magnetospheric convection and magnetopause shadowing effects in ULF wave‐driven energetic electron transport
Download2013
Murphy, Kyle, Degeling, Alex W., Rankin, Robert, Rae, I. Johnathan
Magnetospheric radiation belt electron transport in the presence of ULF waves and a convection electric field is investigated using a model that includes a nightside plasma sheet source and electron losses by magnetopause shadowing. Narrow-band ULF waves launched from a prescribed dayside...

Magnetospheric field‐line resonances: Ground‐based observations and modelingournal of Geophysical Research: Space Physics, 110(A10), [pp
Download2005
Mann, I. R., Kabin, Konstantin, Donovan, E. F., Lu, J. Y., Rankin, Robert, Rae, I. Jonathan, Marchand, Richard
We present theory and ground-based observations of field-line resonances (FLRs) excited in Earth's magnetosphere. Three FLR observations are reported, which correspond to large-scale standing shear Alfven wave (SAW) oscillations on nightside field lines extending from premidnight to close to...

Modeling radiation belt electron acceleration by ULF fast mode waves, launched by solar wind dynamic pressure fluctuations

Rankin, Robert, Degeling, Alex W., Zong, Qui-Gang
We investigate the magnetospheric MHD and energetic electron response to a Storm Sudden Commencement (SSC) and subsequent magnetopause buffeting, focusing on an interval following an SSC event on 25 November 2001. We find that the electron flux signatures observed by LANL, Cluster, and GOES...

Spanswick, Emma, Kabin, Konstantin, Donovan, Eric, Rankin, Robert, Samson, John C.
Significant populations of electrons with energies of tens of keV appear in the Earth's inner central plasma sheet during the substorm expansion phase. Increasing observational evidence indicates that these injections begin at a radially narrow but azimuthally extended transition between very...

Kabin, Konstantin, Rankin, Robert, Fenrich, Frances R., Rae, I. Johnathan., Degeling, Alex W.
This paper presents the results of a linear model for global scale magneto-hydrodynamic (MHD) waves in a compressed dipole model magnetosphere. We examine scenarios where a localized monochromatic source along the magnetopause boundary launches MHD fast mode ultralow frequency (ULF) waves into...

Marchand, Richard, Lu, J. Y., Rankin, Robert, Tikhonchuk, Vladimir T.
Nonlinear dynamics of a dispersive field line resonance (FLR) is investigated in a dipolar magnetic geometry using a new finite element code TOPO. Time dependent dispersion and steepening of the perpendicular Alfvén velocity profile lead to the acceleration of dispersive effects and to...
