Stellar-Atomic Self-Similarity ?

Physicists have imaged the Hydrogen Molecule Wavefunction (squared) for the first time: https://phys.org/news/2018-01-physicists-images-square-function-hydrogen.html

Here is an graphic image:

If you rotate this image through 360 degrees you can get a mental picture of the 3-D shape of the full wavefunction. There is a central propeller-like structure surrounded by barrel-like structure with a narrowed waist.

This shape is for a stable molecule and we are going to compare it with the shapes of systems that are undergoing ionization-like events wherein global ejections of the shells are taking place.

Here are some observational images of planetary nebulae: first some propeller-like shapes and then some barrel-like shapes.

Here is the closest I have come to a combination of the very common PN shapes: propeller and barrel. Then again, I have only searched for a few minutes and one can find a very large number of additional planetary nebulae photos using a Google search.

Then there is this:
