The paper “The impact of kinetic effects on the properties of relativistic electron-positron shocks” by Anne Stockem et al. (2012) was published in Plasma Physics and Controlled Fusion, vol. 54, p. 125004. We show that the transition from a cold upstream to a hot downstream determines the steady state solution of the shock, with deviations of 10% from the standard MHD model. This allows for a quantitative definition of the shock transition region. More information and the full text of the paper can be found here.
