The purpose of the Circumstellar Disk Learning Site (CDLS) is to introduce circumstellar debris disks to students, while also providing enough detail to be considered a significant resource for professional astronomy researchers and instructors. The CDLS was created by Paul Kalas, currently an astronomer at the University of California, Berkeley.
