337. Localized strong energy conversion regions and their use for identifying reconnection sites

Workshop, August 10-14

Invited

In the vicinity of magnetic reconnection, magnetic energy is transferred into kinetic energy. Such a region hence corresponds to a electrical load and it should manifest itself as large and positive values of the power density, E.J>>0, where E and J are the electric field and the current density, respectively. From simple theoretical arguments we find that an event with...

356. Ion temperature anisotropies in magnetotail reconnection jets

Heli Hietala (Imperial College London, UK)

Workshop, August 10-14

Invited

Magnetic reconnection redistributes energy by releasing magnetic energy into plasma kinetic energy - high speed bulk flows, heating, and particle acceleration. A significant portion of the energy released by magnetotail reconnection appears to go into ion heating, and the heating is anisotropic with the plasma temperature parallel to the magnetic field generally increasing more...

387. Wave activities and their roles in collisionless magnetic reconnection

Dr Keizo Fujimoto (National Astronomical Observatory of Japan)

Workshop, August 10-14

Oral

Understanding the wave properties in magnetic reconnection is very important in collisionless plasmas. The waves can transport the momentum and energy between the different species, resulting in the anomalous magnetic dissipation, particle heating, and the formation of non-thermal particles. Observations in the Earth’s magnetosphere and laboratory experiment have shown...
