Magnetopause reconnection across wide local time
During April to July 2007 a combination of 10 spacecraft provided simultaneous monitoring of the dayside magnetopause across a wide range of local times. The array of four Cluster spacecraft, separated at large distances (10 000 km), were traversing the dawn-side magnetopause at high and low latitudes; the five THEMIS spacecraft were often in a 4 + 1 grouped configuration, traversing the low la...
متن کاملExtended magnetic reconnection across the dayside magnetopause.
The extent of where magnetic reconnection (MR), the dominant process responsible for energy and plasma transport into the magnetosphere, operates across Earth's dayside magnetopause has previously been only indirectly shown by observations. We report the first direct evidence of X-line structure resulting from the operation of MR at each of two widely separated locations along the tilted, subso...
متن کاملDynamics of Ganymede’s magnetopause: Intermittent reconnection under steady external conditions
[1] Magnetic reconnection at the terrestrial magnetopause is frequently intermittent, leading to the formation of localized reconnected flux bundles referred to as flux transfer events (FTEs). It remains unclear whether the intermittency of the process is intrinsic or arises because of fluctuations of solar wind properties. Here we use Ganymede’s magnetosphere, which is embedded in a background...
متن کاملMagnetic reconnection and cold plasma at the magnetopause
[1] We report on detailed observations by the four Cluster spacecraft of magnetic reconnection and a Flux Transfer Event (FTE) at the magnetopause. We detect cold (eV) plasma at the magnetopause with two independent methods. We show that the cold ions can be essential for the electric field normal to the current sheet in the separatrix region at the edge of the FTE and for the associated accele...
متن کاملDiamagnetic Suppression of Component Magnetic Reconnection at the Magnetopause
We present particle-in-cell simulations of collisionless magnetic reconnection in a system (like the magnetopause) with a large density asymmetry across the current layer. In the presence of an ambient component of the magnetic field perpendicular to the reconnection plane the gradient creates a diamagnetic drift that advects the X-line with the electron diamagnetic velocity. When the relative ...
