Scientific paper

In order to explain the ion temperature anisotropies and differential speeds observed in solar wind high-speed streams, a fluid-type model is presented that takes account of ion heating and acceleration by resonant wave-particle interactions. Ion-cyclotron and fast magnetosonic waves propagating away from the sun parallel to the interplanetary magnetic field are treated. The radial evolution of the spectral wave energy density and of the bi-Maxwellian model ion distributions is calculated in self-consistent fashion for a spherically symmetric solar wind geometry. Numerical results are presented for the dependence on heliocentric radial distance for the ion parallel and perpendicular temperatures and ion speeds relative to their center of mass frame. The respective ion flow speeds in the inertial frame are also calculated on the basis of momentum equations that include the self-consistent temperature gradients. It is shown that transfer of wave momentum to the ions can result in a preferential acceleration of the alpha particles with respect to the protons.
