They can destroy planets up to Stellar Moon, a special sort of Ringworld I believe (they can also destroy extra huge planets). They cannot destroy Ringworlds or Sphereworlds.

If a stellar moon is destroyed, does the star come back?

No, but you can make a new star.

And create a planet from the asteroid field and build a new stellar moon around the new star. This allows for theoretically infinite planet construction.
