Abstract

Abstract

In this paper, the dispersion relation of MHD waves is analysed for Type-Ⅰcometary tails. The instability of helical waves and its evolution features are studied.In terms of different initial conditions, stable helical waves or irregular clouds may exist in different cometary tails. There is a good consistence between theoretical deduction and observational records. Further research for comet Hale-Bopp may be done based on this work.
