Temperature gradients in fast collisionless magnetic reconnection.
Temperature gradients are shown to deform and shift the magnetic islands that grow during fast collisionless reconnection when electron inertia decouples the plasma motion from the magnetic field. A kinetic electron model describes the collisionless processes during the reconnection of field lines originating in regions with different temperatures. Using a novel model of the reconnecting instability as a surface mode, the kinetic effects are treated analytically in the linear and nonlinear stages of the instability of a current-carrying low-beta plasma slab in a strong magnetic guide field.
