There are numerous examples of this morphology (bipolar nebulae with equatorial jets) found in well-observed planetary nebulae with white dwarf stars. I just liked the viewing aspect and clarity of Eta Carina+Homunculus Nebula.
A white dwarf system is the most common core object for these wavefunction-like envelopes being ejected, but more massive stellar systems can also do the same thing. Just like the ejection of an electron wavefunction is not limited to Helium atoms. And here I claim that a wavefunction is not a probability distribution, but rather is a physical system — a plasma of virtually infinitessimal (relative to the size of the whole system) charged particles. Same for stellar or atomic systems.
