| Abstract: | We use a kinetic collisionless model of the solar wind to calculate the radial variation of the electron temperature and obtain
analytical expressions at large radial distances. In order to be compared with Ulysses observations, the model, which initially
assumed a radial magnetic field, has been generalized to a spiral magnetic field. We present a preliminary comparison with
Ulysses observations in the fast solar wind at high heliospheric latitudes.
