Cylindrical nebulons, symbolic computation and Backlund transformation for the cosmic dust acoustic waves - art. no. 070703

摘要

In a cosmic dusty plasma, the dust-acoustic-wave propagation may be described by a cylindrical Kadomtsev-Petviashvili equation. In this Letter, for such modeling of environments like supernova shells, Saturn's F-ring, etc., cylindrical nebulons and an auto-Backlund transformation are presented via symbolic computation. Nebulon structures are discussed, and possibly observable effects are proposed for cosmic plasmas. (C) 2005 American Institute of Physics.
