The average flow speed of alpha particles relative to protons in the solar wind is observed to be of the order of or less than the Alfven speed. This flow, if sufficiently large, can lead to two distinct types of electromagnetic alpha/proton instabilities: magnetosonic and Alfven. Spatially homogeneous two-dimensional hybrid simulations of collisionless plasmas are used to study these growing modes and the consequent wave-particle scattering of each ion component. This scattering reduces the… CONTINUE READING
