double star designation

(systems and format of double star designators)

There are modern and traditional formats and prefixes for double star designation. Modern efforts such as the Washington Double Star Catalog (WDS) have standardized prefixes (using Latin letters for ease of use in databases and basic printing) usually indicating the discoverer, observatory, or old source astronomical catalog, whereas records going back 200 years used prefixes often consisting of Greek and/or Latin letters, commonly using the Greek equivalent of the credited discoverer's initial. The interest in double stars (as asterisms to serve as guide stars, and regarding movements evident over time) has led to many observations recorded in catalogs and journal letters and papers. These can be very useful for long-term studies of binary star orbits, and the proper motion of optical-double individuals, but using them presents challenges in interpreting both the old-style designators and old coordinates. Some major catalogs of double stars:
