Line-Tied Flux Rope Relaxation and Reconnection: A 3D Kinetic Case Study
Joshua Pawlak, James Juno, Jason M. TenBarge
Magnetic flux ropes are ubiquitous magnetic structures found in plasmas ranging from astrophysical to laboratory. We employ a newly-developed parallel-kinetic-perpendicular-moment…
Phase-Space Energy Transfer of Wave-Particle Interactions using the Field-Particle Correlation Technique and Linear Plasma Theory with JET-PLUME
Collin R. Brown, Gregory G. Howes, Kristopher G. Klein +1
The collisionless transfer of energy between fields and particles through wave-particle interactions is a fundamental process in space plasmas but remains incompletely characterize…
Velocity space origins of pressure-strain interaction in multi-population distributions and its application to magnetic reconnection
M. Hasan Barbhuiya, Paul A. Cassak, Sarah Conley +7
A forefront research question is how energy evolves in weakly collisional plasmas for which departures from local thermodynamic equilibrium (LTE) are significant. The standard appr…
From Weibel seeds to collisionless dynamos beyond pair-plasmas
Lise Hanebring, James Juno, Ammar Hakim +2
Bridging the spatiotemporal scales of magnetic seed field generation and subsequent dynamo amplification in the weakly collisional intracluster medium presents an extreme numerical…
Capturing Secondary Kinetic Instabilities in Three-Dimensional Dayside Reconnection Using an Improved Gradient-Based Closure
Kolter Bradshaw, Ammar Hakim, James Juno +3
Magnetic reconnection is a highly dynamic process that excites a wide variety of kinetic waves and instabilities. Transverse current sheet instabilities such as the lower-hybrid dr…
A Parallel-Kinetic-Perpendicular-Moment Model for Magnetized Plasmas
James Juno, Ammar Hakim, Jason M. TenBarge
We describe a new model for the study of weakly-collisional, magnetized plasmas derived from exploiting the separation of the dynamics parallel and perpendicular to the magnetic fi…
