Boundary Conditions at the Heliospheric Termination Shock with Pickup Ions

In a collisionless shock the directed flow energy is converted mainly in thermal of plasma species. At termination (TS) substantial portion goes into heating pickup ions (PUIs), while solar wind protons (SW) weaker than it would be without PUI. Heating both species nonadiabatic. Downstream pressure mixture determined by conservation laws for whole mixture. SW sensitive to details front, PUI not. The profile an analytical approximation observed TS. Here downstream temperature and PUIs are obtained first time using test particle analysis model various magnetic compression ratios angles. results used balance equation corresponding estimated. supported full simulations, except that was not studied data due its apparent dependence on fine structure front.
