A Case Study of Nonresonant Mode 3-s ULF Waves Observed by MMS
(American Geophysical Union, 2020-11-16)
The nature of the 3-s ultralow frequency (ULF) wave in the Earth's foreshock region and the associated wave-particle interaction are not yet well understood. We investigate the 3-s ULF waves using Magnetospheric Multiscale ...
Reconstruction of Electron and Ion Distribution Functions in a Magnetotail Reconnection Diffusion Region
(American Geophysical Union, 2020-05-23)
In the diffusion region of magnetotail reconnection, particle distributions are highly structured, exhibiting triangular shapes and multiple striations that deviate dramatically from the Maxwellian distribution. Fully ...
Solitary Magnetic Structures at Quasi-Parallel Collisionless Shocks: Formation
(American Geophysical Union, 2020-12-11)
Abstract
Solitary magnetic structures known as SLAMS (short large-amplitude magnetic structures) have been considered as essential elements of collisionless shocks with quasi-parallel geometries. Yet the physics underlying ...
Lower-Hybrid-Drift Vortices in the Electron-Scale Magnetic Reconnection Layer
(American Geophysical Union, 2020-11-10)
Abstract
Lower-hybrid-drift waves driving vortical flows have recently been discovered in the electron current layer during magnetic reconnection in the terrestrial magnetotail. Yet, spacecraft measurements cannot address ...
An improved ten-moment closure for reconnection and instabilities
(AIP Publishing, 2020-08-21)
The integration of kinetic effects in fluid models is important for global simulations of Earth's magnetosphere. The use of the two-fluid ten-moment model, which includes the pressure tensor for both species, has had some ...
Ion-scale Current Structures in Short Large-amplitude Magnetic Structures
(IOP Publishing, 2020-07-30)
We investigate electric current structures in Short Large-Amplitude Magnetic Structures (SLAMS) in the terrestrial ion foreshock region observed by the Magnetospheric Multiscale mission. The structures with intense ...
Exact and locally implicit source term solvers for multifluid-Maxwell systems
(Elsevier, 2020-08-15)
Recently, a family of models that couple multifluid systems to the full Maxwell equations have been used in laboratory, space, and astrophysical plasma modeling. These models are more complete descriptions of the plasma ...
Magnetic reconnection and kinetic waves generated in the Earth's quasi-parallel bow shock
(AIP Publishing, 2020-09-18)
Magnetic reconnection in quasi-parallel shocks, relevant to the Earth's bow shock, is studied by means of two-dimensional full particle-in-cell simulations. As the Alfvénic Mach number increases, the propagation direction ...
Lower-Hybrid Drift Waves Driving Electron Nongyrotropic Heating and Vortical Flows in a Magnetic Reconnection Layer
(American Physical Society, 2020-07-09)
We report measurements of lower-hybrid drift waves driving electron heating and vortical flows in an electron-scale reconnection layer under a guide field. Electrons accelerated by the electrostatic potential of the waves ...
