Scientific paper

The good agreement of the observation results with models shows that the circumstellar dust envelope considered is the repulsed condensated envelope of the progenitor star. The dust distribution is orthogonal with regard to the considered bipolar morphology of the nebula. This distribution of matter is the starting point for the hydrodynamic development of the envelope. It is assumed that the planetary nebula morphology is realized by the interaction of two winds. Hydrodynamic simulations of the two wind model for a discoid envelope show that the quick wind at poles can break through by the shell.
