Frequently Asked Questions

Who is the creator of the double star catalog?

The Washington Visual Double Star Catalog (WDS) is the successor to the Index Catalogue of Visual Double Stars, 1961.0 (IDS; Jeffers & van den Bos, 1963). Three earlier double star catalogs in the 20th century, those by Burnham (BDS; 1906), Innes (SDS; 1927), and Aitken (ADS; 1932), each covered only a portion of the sky.

Where can I find the Washington double star catalog?

Using the resources of the USNO Library, extensive catalog work has been done to include all available measures from 1690 to the present day. Notes to individual systems are also provided. We also, on demand, can prepare custom observing lists suited to the observing capabilities and desires of observers worldwide.

Where can I find list of double stars?

Most of this information is published for every catalogued double star in the Washington Double Star Catalog (WDS), maintained by the United States Naval Observatory (USNO) in Washington, D.C. by Brian Mason and William Hartkopf. This is the most up to date and standard reference for known or suspected visual double stars.

Which is the correct abbreviation for double star?

The one letter to four letter catalog abbreviations used in the Washington Double Star Catalog (WDS) maintained at the United States Naval Observatory are now the standard synonyms for all double star catalogs.
