With four out of four of our solar system's gas giants possessing ring structures, I would expect this to be true and common occurrence with very many star systems we discover that have giant exo-planets in orbit about them.

I wonder if ring structures would be limited to planets that lay beyond a certain distance from their host star or if with some of the giant exo-planets we have discovered so far that are very close to their host star could have ring structures as well. I would have my doubts that giant planets close to their parent star would have ring structures; I would doubt they would have as I think tidal forces from the parent star would prevent this.

Would this be a correct assumption?
