| Abstract: |
We examine the departure from axisymmetry in the structures of several planetary nebulae and proto-planetary nebulae observed with the Hubble Space Telescope. We demonstrate that the departure from axisymmetry can be quantified, despite its complicated nature. We also demonstrate that the departure from axisymmetry can be used to constrain the formation mechanism of the axisymmetrical structure itself. Assuming that the departure was caused by a binary companion, we calculate the required binary system parameters. In most cases the binary companions are within reach of present observational capabilities. |
