Anterograde Collisional Analysis of Solar Wind Ions

The solar wind is ejected out of the Sun at high temperatures and is moving at a high speed, it is not in a local thermal equilibrium. Being a low density and high temperature medium, Coulomb collisions involving the constituent particles within the solar wind dictate that any effect on the dynamics would occur over a relatively long time frame; as the plasma travels further from the Sun the more it thermalizes. Currently the Parker Solar Probe (PSP) is making observations between r = 0.1 - 0.2 AU and the Wind satellite is located at r = 1 AU, since the two separate satellites are in these positions we can analyze the data from PSP and model our predictions. In order to verify the model we analyze and compare with the Wind results to investigate thermalization methods and heating mechanisms in the solar wind.
