| Abstract: | The role of neutrals in a partially ionized collisional dusty plasma is analyzed. In a magnetized inhomogeneous collisional dusty plasma, where plasma components have density gradients, neutrals can affect the instability significantly. Neutral induced instability and the effect of charge variation in such a dusty plasma are investigated. Dust size can control the neutral scale length which can answer the observed density irregularities in the ionosphere. Small sized dust particles favour damping due to charge variation while large sized particles assist collisional damping. |
