Abstract

In Chapter 2 we studied general wave propagation in an infinite, cold, two-component plasma which was characterized by charged particles having no energy except the energy alternately gained and lost as a result of their participation in the wave motion. In this chapter, we restrict our study to the behavior of electrostatic waves propagating parallel to the applied magnetic field in so-called warm plasmas, which are characterized by charged particles having thermal energy. Whereas, for the cold plasma, we found only one purely electrostatic mode, which was simply a (nonpropagating) normal mode of oscillation of the plasma, we find that in a warm plasma the thermal pressure of the particles makes it possible for more than one purely electrostatic mode to exist and causes these modes to be propagating modes.
