In this paper we investigate the effect of changes in the interplanetary magnetic field ( IMF), solar wind dynamic pressure, and dipole tilt angle on the position of the ionospheric projection of the open-closed field line boundary (OCB) in a magnetohydrodynamic (MHD) model. We carry out a large...

An approximate model derived by Hutchinson (2008a), describing the interaction between the solar wind and the Moon, is applied to describe plasma in the lunar wake. The model accounts for plasma entering the wake region from two tangent points around the Moon. Cylindrical geometry is assumed,...

Two‐dimensional hydrodynamic simulations of laser light self‐focusing in a hydrogen plasma are presented. The simulation code includes a model for laser beam propagation which accounts for inverse bremsstrahlung absorption, refraction, diffraction, and ponderomotive forces. A Gaussian hot spot,...

The propagating source method for solving the time-dependent Boltzmann equation describing particle propagation in a magnetically turbulent medium is extended to a more realistic case that includes focusing and adiabatic deceleration. The solutions correspond to beam propagation in the solar...

It is shown that perpendicular gradients in shear Alfvén wave (SAW) dispersion regulate the localization of wave power on nightside geomagnetic L-shells where narrow Field Line Resonances (FLRs) form. We estimate the timescale for this process, ω0tc = 1/equation image, and demonstrate that it is...
