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.
Hey, I don’t disagree, and Eta Carinae is certainly very photogenic. I’m just saying if you talk about white dwarfs and planetary nebulae and then use Eta Carinae as an example, the physical fact that Eta Carinae is not a white dwarf and the Homunculus Nebula is not a planetary nebula is a distraction that takes away from your point. Just pick a planetary nebula if you’re going to talk about the properties of planetary nebulae, or expand the discussion beyond planetary nebulae before you pick a picture of Eta Carinae.
Speaking of more massive systems, it probably doesn’t have to stop at Eta Carinae. Radio galaxies outflows exhibit suspiciously similar geometries.
That said, whether this geometric similarity says anything meaningful about electrons around a helium nucleus is questionable.
