Scientific paper

Our previous study of the solar wind based on a global hybrid model has shown that the effects of kinetic wave-particle interactions may account for the bulk acceleration of the solar wind, the preferential heating of the helium ions over the protons, as well as the occasionally observed double-peaked proton velocity distributions. The model follows the evolution of the particle distributions along an inhomogeneous field line under the effect of ion heating, an ambipolar electric field that is consistent with the particle distributions themselves, and Coulomb collisions. We have suggested that the ion temperatures downstream in the solar wind may highly depend on the location where the wave-particle interactions are the most intense. Here, using our global kinetic approach, we investigate how resonant heating at different heliocentric distances may affect the solar wind downstream, where in-situ experimental data are available. Comparison of our new results with observations will provide a constraint on the location in the solar wind where the majority of wave-particle interactions occurs.
