摘要：
The instability of field-aligned Whistler-mode waves in space plasmas is studied by using a recently developed generalized relativistic kappa-type(KT)distribution.Numerical calculations are performed for a direct compar-ison between the new KT distribution and the current kappa distribution.We show that the wave growth for the KT distribution tends to occur in the lower wave frequency(e.g.,ω(≤)0.1Ω_e)due to a larger fractional num-ber of the resonant electrons ηrel(which controls the wave growth),while primarily locating in the higher wave ...
