Abstract We use the Magnetospheric Multiscale mission to observe a bi‐directional electron acceleration event in foreshock upstream of Earth's quasi‐perpendicular collisionless bow shock. The region is associated with decrease wave activity, inconsistent common mechanisms such as Diffusive Shock Acceleration and Stochastic Drift Acceleration. propose two‐step process where an field‐aligned beam...

The aim of this paper is to develop a new two dimensional time accurate Euler solver for shock tube applications. The solver was developed to study the performance of a newly built short-duration hypersonic test facility at Universiti Tenaga Nasional “UNITEN” in Malaysia. The facility has been designed, built, and commissioned for different values of diaphragm pressure ratios in order to get wi...

The mechanics of a radiative shock which has “collapsed,” or been compressed to high density, via radiative cooling is discussed. This process is relevant to an experiment in xenon gas that produced a driven, radiatively collapsed shock, and also to a simulation of the supernova 1987A shock wave passing through the outer layers of the star and into the low-density circumstellar material.
