The Plasma in the Heliosheath Available to Purchase

This paper describes recent results from Voyager 2 in the heliosheath (HSh). The speed has been constant across the HSh. The density and temperature have decreased, probably due both to a decrease in solar output and deflection of plasma toward the heliotail. Fluctuations in the speed are smaller than in planetary magnetosheaths, probably because of the large size of the HSh reduces the affect of boundary motions. Density and temperatures variations are similar to those in magnetosheaths, suggesting small scale shock oscillations are the similar at bow shocks and the termination shock. Flows are very different at Voyager 1 and Voyager 2; the Voyager 2 data differ from model predictions.
