Proton temperature distribution in the dynamic heliosphere (Scherer & Ferreira 2005). Above the solar pole the features of a high-speed stream can be identified. Because of the influence of the PUI_SH⁺ the temperature inside the termination shock is a few 10⁵ K, corresponding to thermal energies of up to a few tens of eV. The temperature in the inner heliosheath is 10⁶ K, which was inferred by IBEX (Livadiotis et al. 2011).
