Abstract
We derive the flow properties of the solar wind using a two-fluid model constrained by the density gradients inferred from white light observations of a south polar coronal hole on 11 April 1993 during the SPARTAN 201-1 flight, and interplanetary observations, e.g. from Ulysses’ south polar passage. We present the results of model computations for which we get the best fit to these data. One of the main results of this study is that, for the same energy input to electrons and protons, the proton temperature can be significantly higher than the electron temperature in the inner corona. In addition, we show that different functional forms of the energy addition with the same total energy input can yield different solar wind parameters at 1AU.
