Of the fifty-seven stars included in the new almanac, these two had no traditional names. The RAF insisted that all of the stars must have names, so new names were invented for them. [8] These names have been approved by the IAU WGSN. [2] The book Star Names: Their Lore and Meaning by R. H. Allen (1899) [9] has had effects on star names:
In 2016, the International Astronomical Union (IAU) organized a Working Group on Star Names (WGSN) [2] to catalog and standardize proper names for stars. The WGSN's first bulletin, dated July 2016, [3] included a table of 125 stars comprising the first two batches of names approved by the WGSN (on 30 June and 20 July 2016) together with names of stars adopted by the IAU Executive Committee ...
The number used to identify stars in navigation publications and star charts. [Note 2] Common name The name of the star commonly used navigation publications and star charts. Bayer designation: Another name of the star which combines a Greek letter with the possessive form of its constellation's Latin name. Etymology of common name
In the early 19th century few variable stars were known, so it seemed reasonable to use the letters of the Latin script.Because very few constellations contained stars with uppercase Latin-letter Bayer designation greater than Q, the letter R was chosen as a starting point so as to avoid confusion with letter spectral types or the (now rarely used) Latin-letter Bayer designations.
Variable stars are assigned designations in a variable star scheme that is based on a variation of the Bayer designation format, with an identifying label preceding the Latin genitive of the name of the constellation in which the star lies. Such designations mark them as variable stars.
λ Scorpii (Latinised to Lambda Scorpii) is the star system's Bayer designation. It bore the traditional name Shaula, which comes from the Arabic الشولاء al-šawlā´ meaning 'the raised [tail]', as it is found in the tail of Scorpius, the scorpion. In 2016, the International Astronomical Union organized a Working Group on Star Names ...
