Numerical simulations on the magnetopause current layer

Description: One-dimensional particle simulations are carried out in order to study the current layer between a plasma and magnetic field such as seen at the magnetopause boundary layer. When a subsonic solar wind plasma flow impinges upon a vacuum dipole magnetic field, the width of the current layer is found much smaller than the ion gyroradius and is close to theoretically predicted geometric mean of the ion and electron gyroradii. The width remains essentially the same when the magnetic field is filled … more

Substorms: Their expansion and recovery phases

Description: Solar flares and magnetospheric substorms are each presumably processes by which energy is released from storage in magnetic fields and converted into kinetic energy of plasma and energetic particles. There are a number of analogies between flares and substorms. This paper briefly discusses substorms, their expansion and recovery phases, and a model by which they are presently explained. Two features of substorms, the retreating neutral line'' and the separatrix layer'' are offered as features … more
