Effect of Two Different Electron Temperatures in Auroral Ionosphere
Keywords:auroral plasma, electron temperature, electron-acoustic wave, lower-hybrid wave
We have investigated the effect of two different electron temperatures in an auroral ionosphere in the presence of ions and obtained a modified electron-acoustic and modified lower-hybrid drift dissipative modes which will not be affected much due to the presence of cold electrons. However, in the drift dissipative case, the growth rate of the electron-acoustic wave depends on the number density of cold electrons.
