Field line distribution of mass density at geostationary orbit 

Denton, R. E.; Takahashi, Kazue; Lee, Jimyoung; Zeitler, C. K.; Wimer, N. T.; Litscher, L. E.; Singer, H. J.; Min, Kyungguk; 0000-0002-2095-8529 (2020-06-05)
The distribution of mass density along the field lines affects the ratios of toroidal (azimuthally oscillating) Alfven frequencies, and given the ratios of these frequencies, we can get information about that distribution. ...

One- and two-dimensional hybrid simulations of whistler mode waves in a dipole field 

Wu, S.; Denton, R. E.; Liu, Kaijun; Hudson, M. K.; 0000-0001-5882-1328 (2020-06-05)
We simulate whistler mode waves using a hybrid code. There are four species in the simulations, hot electrons initialized with a bi-Maxwellian distribution with temperature in the direction perpendicular to background ...

Test-Particle Simulations of Linear and Nonlinear Interactions Between a 2-D Whistler-Mode Wave Packet and Radiation Belt Electrons 

da Silva, C. L.; Denton, R. E.; Hudson, M. K.; Millan, R. M.; Liu, K.; Bortnik, J. (2020-05-27)
Using test-particle simulations, we describe (in 2-D) the interaction of an ensemble of electrons with a discrete whistler-mode wave packet, which propagates with a moderate wave-normal angle with respect to the background ...
