There’s an interesting program on the Discovery channel called ‘How the Universe Works’...they had an episode on that posited an explanation of how a Jupiter-like planet could have gotten so close to the parent star...it seems the enormous gravity of the star and the planet create a harmonic convergence wave, similar to ripples in a pond when you throw in a stone, that the planet ‘rides’ inbound; sound like this might be a similar situation, if this isn’t indeed the star/planet they were talking about on the show; sounded plausible enough, I guess.
It surfed in on a Gravity Wave....................dude..........
