The effect of the hot, anisotropic magnetospheric protons on the dispersion relation

It is shown that the presence of hot, anisotropic protons of ring current in outer plasmasphere lead to the modification of the dispersion of A- and FMS-waves in the low frequency region. In this case, a periodic instability of A-waves is observed, and during their propagation, the change of polarization is possible. This can explain the presence of right-hand polarization waves in the ring current zone.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/30856/1/0000519.pd
