Evolution of magnetic helicity under kinetic magnetic reconnection:Part II B≠0 reconnection
magnetic helicity kinetic magnetic reconnection B≠0 reconnection
2009/11/12
We investigate the evolution of magnetic helicity under kinetic magnetic reconnection in thin current sheets. We use Harris sheet equilibria and superimpose an external magnetic guide field. Consequen...
Two-dimensional MHD model of the reconnection diffusion region
Two-dimensional MHD model reconnection diffusion region
2009/11/12
Magnetic reconnection is an important process providing a fast conversion of magnetic energy into thermal and kinetic plasma energy. In this concern, a key problem is that of the resistive diffusion r...
Developments in the theory of collisionless reconnection in magnetic configurations with a strong guide field

2009/11/11
We review some recent results that have been obtained in the investigation of collisionless reconnection in two dimensional magnetic configurations with a strong guide field in regimes of interest for...
We present new diagnostics of the solar flare reconnection, mainly based on the plasma radio emission. We propose that the high-frequency (600-2000 MHz) slowly drifting pulsating structures map the fl...
Electrodynamics in a very thin current sheet leading to magnetic reconnection
thin current sheet magnetic reconnection
2009/11/9
We study the formation of a very thin current sheet (CS) and associated plasma electrodynamics using three-dimensional (3-D) particle-in-cell simulations with ion to electron mass ratio M/m=1836. The ...
Coupling between reconnection and Kelvin-Helmholtz instabilities in collisionless plasmas
reconnection Kelvin-Helmholtz instabilities collisionless plasmas
2009/10/30
In a collisionless plasma, when reconnection instability takes place, strong shear flows may develop. Under appropriate conditions these shear flows become unstable to the Kelvin-Helmholtz instability...
Solar wind interaction with the Earth's magnetosphere:the role of reconnection in the presence of a large scale sheared flow
Solar wind interaction Earth's magnetosphere role of reconnection large scale sheared flow
2009/10/30
The Earth's magnetosphere and solar wind environment is a laboratory of excellence for the study of the physics of collisionless magnetic reconnection. At low latitude magnetopause, magnetic reconnect...
