On the upconversion of ion-sound to Langmuir turbulence
Abstract
Consideration is given to the upconversion of ion sound waves to excited Langmuir waves in solar flares. It is shown that, due to the process of anomalous high-frequency resistivity in which the reabsorption of Langmuir waves in the presence of ion waves is enhanced, the upconversion of ion sound waves to Langmuir waves is impossible in the absence of suprathermal particles and when the electron drift velocity is less than the electron thermal velocity.
