Collisionless tearing instability of a bi-Maxwellian neutral sheet with exact particle orbits. Interim report
The tearing instability of a neutral sheet may be important to reconnection in the magnetosphere and elsewhere. The use of a bi-Maxwellian Harris equilibrium is broadly applicable to the physical environment and allows a continuous variation from isotropic situations. The integro-differential equation describing the linear tearing instability in the bi-Maxwellian neutral sheet is solved without approximating the particle orbits. Results of this calculation are presented. Comparison between the exact solution and the 3-region approximation motivates the piecewise-straight-line approximation, a simplification which allows faster solution of the integro-differential equation, yet retains the important features of the exact solution.
