A PARALLEL-PROPAGATING ALFVÉNIC ION-BEAM INSTABILITY IN THE HIGH-BETA SOLAR WIND
2013
Astrophysical Journal
We investigate the conditions under which parallel-propagating Alfv\'en/ion-cyclotron waves are driven unstable by an isotropic ($T_{\perp \alpha} = T_{\parallel\alpha}$) population of alpha particles drifting parallel to the magnetic field at an average speed $U_{\alpha}$ with respect to the protons. We derive an approximate analytic condition for the minimum value of $U_{\alpha}$ needed to excite this instability and refine this result using numerical solutions to the hot-plasma dispersion
