| Zusammenfassung |
| We study the wave-particle interaction and the evolution of
electromagnetic waves propagating through a plasma composed of
electrons and protons, using two approaches. First, a quasilinear
kinetic theory has been developed to study the energy transfer
between waves and particles, with the subsequent acceleration and
heating of protons. Second, a one-dimensional hybrid numerical
simulation has been performed, with and without including an
expanding-box model that emulates the spherical expansion of the
solar wind, to investigate the fully nonlinear evolution of this
wave-particle interaction. Numerical results of both approaches
show that there is an anisotropic evolution of proton temperature. |
