Like a study of the three bodied problem as opposed to the two bodied problem with it's simple barycentre. Once the three bodied problem is understood, it can be generally applied to the solar system. Frankly I am a bit surprised modern researchers are even arguing about it. As koan would say... It's "settled science" or at least should be -g- So I am a bit unsettled the science is not yet settled, if you get my drift. In undergraduate physics, it's rare to go outside the two bodied problems as it's complicated and just a "perturbation". a small change. That all got a big shake up when Chaos Theory arrived with the strange thinking of Mitchell Feigenbaum in 1974, and elsewhere. Then came the new fangled computers and a more intense study of non linear equations... equations that kept coming up with different answers. Things indeed got perturbed, and in a lot of cases went chaotic. If I have read Zharkova correctly, she independently came up with an extra 2200 year cycle that needed explaining away. Then she found the Hallstatt's cycle and that is why she is sticking to her guns on that particular approach. That is my current understanding, but watch this space. Back to the literature.. lots of references to the Hallstatt Cycle. <<We therefore concluded that this so-called Hallstatt periodicity most likely reflects some periodicity in the solar activity .>> Solar activity during the Holocene: the Hallstatt cycle and its consequence for grand minima and maxima | Astronomy & Astrophysics (A&A) Lots of cycles mentioned here, Hallstatt is somewhere near the bottom. Solar cycle - Wikipedia So worthy of a look over the next month or two, for me anyway.
