Welcome to the CBS Database!

This web-based interactive database is being developed and maintained by a team at the Sternberg Astronomical Institute of the Moscow State University. The project is an on-line extension of our catalogue on "Highly Evolved Close Binary Stars" (volumes I, II) published by Gordon and Breach in 1996.

As of September 2009, the database (both the software and the content) is in its development/testing phase.
