Seems Edgeworth-Kuiper Belts are more common than regular star-systems, at least around A stars…
Universe may abound with icy planets (from COSMOS magazine.)
…A stars are like Sirius A and Fomalhaut (stellar celebrity with a planet now spotted by the HST), substantially brighter than the Sun, not heavy enough to get dramatic and go SuperNova. Instead they race through the Main Sequence and become Red Giants in less than a billion years. So while the belts of Icy Planets are currently chilled, eventually they will melt down and become rather nice for a few million years before their stars sputter out.
