Over the past few years, astronomers have found an incredible diversity in the architecture of exoplanetary systems, as well as the planets themselves. A survey using the sharp view of the Hubble Space Telescope has uncovered a similar diversity in the debris systems that coincide with the formation of exoplanets. These circumstellar dusty disks are likely generated by collisions between objects left over from planet formation around stars. The survey’s results suggest that there is some sort of interdependence between a planet and the accompanying debris system.
