Simulations of Wave Particle Interactions in the Expanding Solar Wind in 1 and 2 Dimensions.
Abstract
We present hybrid simulations of the interaction of Alfvén and ion cyclotron waves with protons and helium in the accelerating solar wind using the expanding box model. We study how mirror force and wave-particle interactions compete in shaping the distribution function both for protons and minor ions for a range of initial fluctuation spectra and propagation directions in 1 and 2 dimensions. The simulations are discussed within the context of analytical and numerical models of the evolution of MHD turbulence in the outer corona and accelerating solar wind, with the aim of constraining the possible initial conditions leading to the observed in situ evolution.
