Abstract
Irradiation effect on the different plasma modes in various dusty plasma conditions was studied theoretically. We revisit our investigation on the instability of the electrostatic dust acoustic (DA) mode elaborately in the case of ionospheric dusty plasmas. In this investigation, it is found that the growth rate of DA mode increases two orders more due to the photoelectric effect than that of the streaming effect. A detailed description of the dust charge fluctuation model in the irradiated dusty plasmas, the derivation of the DA mode, and discussions on the numerical analysis of the obtained results make the paper easy to understand. The present theory should be applied specially in understanding the formation of radar echoes in the presence of solar radiation.
