The shape of this graph corresponded to another graph I had seen. On page 124 of "Lost Star of Myth and Time" is a graph of the rate of precession over much of the last century.
I believe the graphs are too similar to be coincidence.
Why should changes in Arcturus temperature correspond to changes in the rate of precession? The amount of E-M put out by a star is a function of it's temperature. If precession is caused by the solar system spiraling through the magnetic field of a star,then an increase in that star's E-M field (and hence temperature) should cause an increase in the rate of precession.
Arcturus IS controling the path of the sun!

This stream is not in the plane of the Milky Way galaxy and is likely the remnants of an ancient dwarf satellite galaxy, long since disrupted and assimilated into the Milky Way. It consists of old stars deficient in heavy elements.
"We've confirmed the Arcturus moving group as being a star stream, which indicates a disruptive galaxy spiralled into our own," he says.

It describes the heating or cooling of a current-carrying conductor with a temperature gradient.
Any current-carrying conductor (except for a superconductor), with a temperature difference between two points, will either absorb or emit heat, depending on the material...
In metals such as zinc and copper, which have a hotter end at a higher potential and a cooler end at a lower potential, when current moves from the hotter end to the colder end, it is moving from a high to a low potential, so there is an evolution of heat. This is called the positive Thomson effect.
In metals such as cobalt, nickel, and iron, which have a cooler end at a higher potential and a hotter end at a lower potential, when current moves from the hotter end to the colder end, it is moving from a low to a high potential, there is an absorption of heat. This is called the negative Thomson effect.

a) The Past. ...If, however the effective temperature of the star is as high as the new measurements claim, then all the analyses will have underestimated its metal content by quite serious factors.
Therefore, either astrophysicists are getting steadily nearer to, or further from, astrophysical reality or Arcturus is hotting up for some evolution of its own.

A few conjectures. Feel free to refute etc as I'm not particularly partial.
In relation to Arcturus being oppositely charged:
Arcturus is often considered to be a "Red Giant"; pg. 80 of The Electric Universe sheds further light on that topic. Here, the "Red Giant" phase is due to "profound electron deficiency". In order to acheive balance:... it must collect more electrons than the plasma can deliver continuously to its surface. So the anode responds by expanding its influence, forming a negative space-charge sheath (plasma cell or double layer).
... as the sheath expands, its electric field will grow stronger and stronger.

...when seen in electric terms, instead of being near the end point of a star's life, a red giant may be a 'child' loosing sufficient mass to begin the next phase of its existence - on the main sequence.
When considered as a "passing star", this is the way some articles have characterized Arcturus and its "stellar stream", and relation to potentially being the product of some sort of 'merger' perhaps the fluctuations of Arcturus' red giant phase stems from adaptations to what would be its relatively new galactic enviroment - as it continues to acclimate itself to a different electrical potential?
In such a case it seems the hypothesis cited above could also beget a star which forms an expansive negative space-charge sheath in order to satisfy its "electron deficiency". How would the resulting electric field affect existing stars in the "local bubble"? It seems that the e-field could be a driving force causing the existing stars of the local region ('electrical 'node') to increase electrical output to 'feed' the new arrival.
I'm a bit hesitant to say which affects the other more when the relationship appears to be reciprocal. As a red giant the over all current density of Arcturus would be low, spread out over a much larger surface etc. Our Sun on the other hand has a high current density on approach and when taken in conjunction with the other stars in the "local fluff" Arcturus would seem to have quite a bit of resource to draw from in that regard.
At 36.7 light years, or so, away (pretty close distance as space goes) I would also more inclined to think that an aggregate portion of the Arcturus Stream could cause an increase in local electrical output as opposed to the one star. This, by requiring the existing local node to be 'back fed' from the sources of its own electrical dependancy replinishing what Arcturus and its stream might deplete as it acquires surface area to meet the electron deficiency. This would also seem to be able to account for the "power generator" that could cause our solar system to precess faster while simultaneously increasing the temperature of Arcturus.
Interestingly, the "Local Bubble" as described by the "Internet Encyclopedia of Science" contains a small map for the region. The caption has interesting statements characterizing 'walls' of surrounding "dark mode" plasma in relation to the local cavity:Notice that the local cavity is surrounded by many of these condensations, but this "wall" is broken in several places by low density interstellar tunnels that link the local cavity with other nearby bubble cavities such as the Pleiades and GSH 238+00+09.

In an ideal state it would seem that the "bubbles" are balanced according to their relative elecrical properties i.e. double layers, e-fields, Langmuir sheaths, homogeneity, etc. Change the electrical perameters in one local region, and perhaps the others could probably electrically compensate via current flow through these "tunnels" resulting in the perception of the sun entering a part of space where forces on it are greater,increasing spiraling motion of solar system (precession)."
I wonder if Voyager would be able to discern a stellar 'wind' originating from the direction of Arcturus once it passes our heliosheath all together?
Lastly, here is another paper concerning The Temperature of Arcturus which I've only scanned. I'm hoping that it may answer some questions as to whether or not the temperature of Arcturus actually increased or perhaps measuring techniques inadvertently resulted in lower temperatures for previous studies. Section 4. "Discussion and conclusions" seems to hint at this.

It would seem to me that a brown dwarf at 1000 AU [would be outside the Sun's plasmasphere which extends to about 100 AU (?)] and would be shining with it's own light, and be visible from Earth, at least telescopically (at a magnitude well within the range of a backyard telescope.) I would think that it would have been discovered by an observatory by now, as the skies have been searched with machines that blink photos, taken at different times, for many years looking for new planets. But then perhaps I am overestimating it's luminosity.
