IAWs are like Langmuir waves but where the ions oscillate in a longitudinal fashion. The electrons serve to counter the ion oscillations to prevent charge accumulation. If just the electrons oscillate, then the real part of the frequency would be near fpe not fpi. These would damp differently than an IAW too. | |

In the 1970s and 1980s, several authors (e.g., Christian Dum) did a lot of work on this topic and found that the instability dependence on $T_{e}/T_{i}$ could be reduced or even ignored in the presence of electron heat fluxes, temperature gradients, beams, etc. Note that the original concept is horribly flawed in that we never observe single, isotropic Maxwellians for either ions or electrons in space plasmas. | |
