Yeah, but they're usually not in so close- wobble that's detectible is not what I really meant- I mean does the planet affect the star to the point where the star's gravitational field "skews" and causes everything else in the system to have wildly erratic orbits?
Sorta like how a dense body ("Planet X"?) supposedly interferes with Uranus' orbit, making plotting it's exact position problematic.

Yeah, I'm just sorta shooting for a point (and missing).

I think you're just going for wondering whether the star has an extreme wobble, or, maybe, a very erratic orbit about the galactic center?

I was thikning that the proximity to the dense planet might make the star move erraticly: a binary system might have stars that move around a point between them, in this case, I was thnking the dense planet's orbit may (when it's orbit is closest to the star) cause the star to move in a way we've not seen before.
Or maybe the planet causes massive eruptions as it gets closer and pulls away... Or maybe the stars are just pinpricks in the cloth of the night sky which shields us from the unbearable light of heaven- light which would give our very souls terminal cancer (which would be a bad thing in my opinion).

Oh - you mean the center of gravity of the system of the planet and it's host star would be outside both their radii? Like, the point they orbit around is not contained within the star.

Yes, something like that, only it's not a continous thing- the two dont orbit each other or anything- it's only when the dense planet dips in close during it's orbit.

The center of gravity of a two-body system shifts around. I mean it really can't stay still. Really in every single two-body system they orbit each other; even an infinitesimal amount of mass orbiting a massive dense thing will pull its center of gravity away from its center of mass just a tiny, tiny, tiny tiny bit.
