An Extended MHD Study of the 16 October 2015 MMS Diffusion Region Crossing
(American Geophysical Union, 2019-09-09)
The Magnetospheric Multiscale (MMS) mission has given us unprecedented access to high cadence particle and field data of magnetic reconnection at Earth's magnetopause. MMS first passed very near an X-line on 16 October ...
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 ...
The island coalescence problem: Scaling of reconnection in extended fluid models including higher-order moments
(AIP Publishing, 2015-11-05)
As modeling of collisionless magnetic reconnection in most space plasmas with realistic parameters is beyond the capability of today's simulations, due to the separation between global and kinetic length scales, it is ...
Role of Ion Kinetic Physics in the Interaction of Magnetic Flux Ropes
(American Physical Society, 2015-10-21)
To explain many natural magnetized plasma phenomena, it is crucial to understand how rates of collisionless magnetic reconnection scale in large magnetohydrodynamic (MHD) scale systems. Simulations of isolated current ...
The role of guide field in magnetic reconnection driven by island coalescence
(AIP Publishing, 2017-02-24)
A number of studies have considered how the rate of magnetic reconnection scales in large and weakly collisional systems by the modelling of long reconnecting current sheets. However, this set-up neglects both the formation ...
Drift Instabilities in Thin Current Sheets Using a Two-Fluid Model With Pressure Tensor Effects
(American Geophysical Union, 2019-04-15)
The integration of kinetic effects in fluid models is important for global simulations of the Earth's magnetosphere. We use a two-fluid 10-moment model, which includes the pressure tensor and has been used to study ...
Simulations of anti-parallel reconnection using a nonlocal heat flux closure
(AIP Publishing, 2017-08-08)
The integration of kinetic effects in fluid models is important for global simulations of the Earth's magnetosphere. In particular, it has been shown that ion kinetics play a crucial role in the dynamics of large reconnecting ...
Using the maximum entropy distribution to describe electrons in reconnecting current sheets
(AIP Publishing, 2018-08-17)
Particle distributions in weakly collisional environments such as the magnetosphere have been observed to show deviations from the Maxwellian distribution. These can often be reproduced in kinetic simulations, but fluid ...
