Abstract
We have computed the dispersion relation for low-frequency dust-acoust ic waves including dust charge variation. A phase difference between t he dust charge variation and the wave can lead to a strong damping of the wave. We present analytical expressions for the wave dispersion an d the damping rate for dust-acoustic waves in a not too dense dusty pl asma and discuss possible applications of the theory for dust waves in planetary dust rings.
