Scaling of Driven Magnetic Reconnection Rates
Computational experiments in various collisionality regimes show that, when the drive is unambiguously separated from the reconnection region, driven magnetic reconnection, in its idealized and extensively studied two dimensional form, proceeds at a rate determined only by the boundary conditions. Within certain bounds, details of the physics model used in studying this ubiquitous phenomenon pl...
متن کاملScaling of asymmetric Hall magnetic reconnection
[1] The scaling of the reconnection rate and ion and electron outflow speeds with upstream magnetic field strengths and plasma mass densities during asymmetric collisionless (Hall) reconnection without a guide field is studied using two-dimensional two-fluid simulations. The results agree with a recent theory by Cassak and Shay (2007). It is found that the normalized reconnection rate is on the...

متن کاملScaling of asymmetric magnetic reconnection: Kinetic particle‐in‐cell simulations
[1] Recently, Cassak and Shay (2007) applied a generalized Sweet‐Parker analysis to derive scaling laws for gross properties of asymmetric magnetic reconnection, including the reconnection rate, outflow speed, and outflow density. This study presents the first comprehensive test of this scaling theory using fully electromagnetic particle‐in‐cell simulations of antiparallel asymmetric magnetic r...
متن کاملThe scaling of collisionless, magnetic reconnection for large systems
Hybrid simulations with electron inertia, along with analytic scaling arguments, are presented which demonstrate that magnetic reconnection remains Alfv6nic in a collisionless system even as the macroscopic scale length of the system becomes very large. This fast reconnection is facilitated by the whistler physics present near the x-line. The reconnection rate is found to be a universal constan...
