If Kármán vortices are responsible for pushing and pulling the sun to inner and outer positions, does that mean that the sun is being pulled in a fluid around some kind of central vortex? If so, what is the fluid, and what causes that vortex?
The space-time medium ("aether" is so looked down upon these days, don't you know)? Or specifically the flow of that medium due to the *universal accelerator ", "aetheric wind", "dark energy" , etc
The vortex is formed as the flow separates passing the earth.
Yes, the idea of Aether has been generally superseded by relatively, because relatively explains observations better.
But Luminiferous Aether was thought to be a medium for light to propagate in, that doesn’t interact with mass.

Whatever you are proposing would have to be very different from the Aether Newton subscribed to. Einstein sometimes used the term Aether to describe space time, but that is different again. Perhaps you want to go back to ancient definitions of Aether, when it was thought to be more like a physical fluid?
Some clarification would be helpful.
Maybe I should rephrase my above question, it wasn’t very clear. Are you suggesting that these vortices cause the motion of the sun in its daily circuit? Or just the seasonal changes to that motion?
Not that complicated, my arse. A real explanation for this would be very complicated.
"Real explanations" of celestial mechanics tend to be very complicated, yes... See, three-body problem.
A simple explanation, however, is often quite simple. As above.
Calculating the trajectory is complicated, but the basic principle is very simple:
Momentum + Gravity = Orbits
That’s really all I need to be able to visualize the motions in the solar system.
Whereas your Kármán vortices answer doesn’t give me nearly enough to see how it’s supposed to work. Maybe there’s more to it? I don’t know.
If you know of a more detailed explanation, I’d be genuinely interested.
