A Three-Dimensional Magnetohydrodynamic Model of Planetary Nebula Jets, Knots, and Filaments
arXiv:0803.4518 · doi:10.1051/0004-6361:200809848
Abstract
The morphologies of planetary nebulae are believed to be self-organized configurations. These configurations are modeled by three-dimensional temporally self-similar magnetohydrodynamic solutions with radial flow, under the gravitational field of a central star of mass . These solutions reproduce basic features, such as jets, point-symmetric knots, and filaments, through plasma pressure, mass density, and magnetic field lines. The time evolution function of the radial velocity starts as a slow wind and terminates as a fast wind.
