Density jump as a function of magnetic field for switch-on collisionless shocks in pair plasmas

The properties of collisionless shocks, like the density jump, are usually derived from magnetohydrodynamics (MHD), where isotropic pressures assumed. Yet, in a plasma, an external magnetic field can sustain stable anisotropy. In \cite{BretJPP2018}, we devised model for kinetic history plasma through shock front, allowing to self-consistently compute downstream anisotropy, hence terms upstream parameters. This dealt with case parallel shock, is normal front both and downstream. MHD also allows solutions, so-called switch-on only upstream. article consists applying our these shocks. While offers 1 solution within limited range Alfv\'{e}n Mach numbers, 2 kinds solutions slightly different numbers. These most likely outcome intermediate fast shocks under model. merge case, they do not For simplicity, formalism restricted non-relativistic pair plasmas cold.
