This theory elegantly explains the structue of one of the known planetary systems, but as far as I can tell forbids the structure of most other known planetary

  I suspect a larger hole in this theory is all the "dwarf planet(s)" (ex: pluto) that don't look like small gas giants. I mean nothing prevents a star from capturing a “rogue planet / proto star” and if you look at younger systems you might seem more inner gas giants etc. But, there are several proto planets that don’t seem to fit with the theory. PS: Then again they could have formed around another star…

  From a theory that relies on the impossibility of gas giants staying gas giants near a star, I'd expect some arguments as to why all the observed gas giants that are extremely close to their stars do not invalidate it. I read the preprint, but it's a little iffy on the idea of how the removal of the outer layers is supposed to work. But I think the idea is that a small gas giant would lose its outer layers if brought in from the outer solar system, while a Jupiter-sized one wouldn't. Still, the preprint makes no reference to hot Jupiters whatsoever, which seems to be a major oversight. It's no good crowing about how your model explains one planetary system without even mentioning what it says about others. I don't much like this model, myself.
