The role of alpha particles in the emission of plasma waves inside solar ejecta

Mostrar todas las versiones(3)

The enhancement of the resonant instability of right-hand polarized electromagnetic ion cyclotron waves by alpha particles for physical parameters corresponding to coronal mass ejections is studied. We focus on the effects of alpha thermal anisotropy and relative He++/H+ abundance on growth and abso...
