349. Numerical simulation of collsionless magnetic reconnection and its coupling to turbulent and kinetic processes

Workshop, August 10-14

Invited

Magnetic reconnection is a multi-scale phenomenon which in collisionless plasmas involves electron and ion kinetic processes as well as macro-scale plasma flows. Only numerical simulation approaches allow to bridge the huge scale- gaps between the relevant particle and flow dynamics. We review the different approaches taken so far to cope with the arising difficulties and draw...

345. Particle acceleration in turbulent magnetic reconnection

Prof. Masahiro Hoshino (The University of Tokyo)

Workshop, August 10-14

Keynote

Nonthermal particles are ubiquitous in space and astrophysical plasmas, and explosive phenomena such as supernova remnant shocks, solar flares, and terrestrial substroms have demonstrated evidence for the production of high-energy particles. Yet the particle acceleration mechanism remains an unresolved issue. After the innovative idea of the stochastic acceleration by Enrico...

360. Characterization of Magnetic discontinuities from MHD to sub-proton scales

Dr Antonella Greco (Physics Department, University of Calabria, Italy)

Workshop, August 10-14

Oral

The intermittent properties of the turbulent field at different scales down towards electron scales have been studied using CLUSTER magnetic field data in solar wind. We found that turbulence, in some cases, orginizes itself in unidimensional current sheets well descibed by an Harris equilibrium on electron scales. These structures could be those structures that numerical...
