Description
When applied to compute the density jump of a shock, the standard magnetohydrodynamic (MHD) formalism assumes that all the upstream material passes downstream, together with the momentum and energy it carries, and that pressures are isotropic. In a collisionless shock, shock-accelerated particles going back and forth around the front can invalidate the first assumption. In addition, an external magnetic field can sustain stable pressure anisotropies, invalidating the second assumption. Therefore, it is unclear whether or not the density jump of a collisionless shock fulfills the MHD jump. Posible consequences in ICF will be commented.
