Exoplanetary Circumstellar Environments and Disk Explorer(EXCEDE) is a proposed space telescope for NASA's Explorer program to observe circumstellar debris discs and study planet formation around nearby stars. The spacecraft will use a 70 centimeter diameter telescope-mounted coronagraph called PIAA (Phase Induced Amplitude Apodized Coronagraph) to suppress starlight in order to be able to detect fainter radiation of circumstellar dust. Characterizing constitution of such disks would provide clues for planetary formation, while already existing exoplanets can be detected through their interaction with dust disk.
