`Are there other planetary systems like ours? Other planets like ours? Is there life elsewhere in the Universe?' So asks Dr. Lew Allen Jr. in the Foreword. In December of 1992, theorists, observers, and instrument builders gathered at the California Institute of Technology to discuss the search for answers to these questions. The International Conference, entitled `Planetary Systems: Formation, Evolution, and Detection' and supported through NASA's newly formed TOPS (Toward Other Planetary Systems) program, was the first of a series of conferences uniting researchers across disciplines and political boundaries to share thoughts and information on planetary systems. The conference was sponsored by NASA, hosted by JPL at Caltech, and endorsed by the 1992 International Space Year Association. These proceedings include discussions of topics ranging from stellar, disk, and planetary formation to new ways of searching for other stellar systems containing planets. The authors represent a wide range of nationalities, disciplines, and points of view. The second international conference took place in December of 1993.

Papers from an international conference supported through NASA's newly-formed TOPS (Toward Other Planetary Systems) program. Theorists, observers, and instrument-builders gathered to discuss questions like whether there are other systems like ours, other planets like ours, and whether there is life elsewhere. Topics include formation and properties of fluffy planetesimals, planets around pulsars, synthetic images of proto-planetary disks, differential astronomy with large telescopes, and the circumstellar imager.
