So what are the alternatives? I'm not going to pretend I understand the science behind my postulations, but my fuzzy mental image is that it must be some form of wave-wave interactions, perhaps with other mechanisms not
presently identified. Aren't these links suggestive of such a process?
Non-linear wave-wave interactions:
In this paper we present evidence for the nonlinear wave-wave interactions
involving electrostatic electron plasma (Langmuir) waves in the Solar wind,
ion acoustic waves, and, possibly, transverse electromagnetic waves.
