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 ...
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:
The internal structure of a main sequence star depends upon the mass of the star. In stars with masses of 0.3–1.5 solar masses (M ☉), including the Sun, hydrogen-to-helium fusion occurs primarily via proton–proton chains, which do not establish a steep temperature gradient. Thus, radiation dominates in the inner portion of solar mass stars.
All of these stars have multiple valid names or catalogue designations. The table lists their Bayer designation and the most common proper name. Most of the proper names have been approved [8] by the Working Group on Star Names of the International Astronomical Union (IAU). Popular names which have not been approved by the IAU are omitted.
In astronomy, star names, in contrast to star designations, are proper names of stars that have emerged from usage in pre-modern astronomical traditions. Lists of these names appear in the following articles: List of Arabic star names; List of Chinese star names; List of proper names of stars: traditional proper names in modern usage around ...
The slash stars are O-type stars with WN-like lines in their spectra. The name "slash" comes from their printed spectral type having a slash in it (e.g. "Of/WNL") [71]). There is a secondary group found with these spectra, a cooler, "intermediate" group designated "Ofpe/WN9". [71]

All stars but one can be associated with an IAU (International Astronomical Union) constellation. IAU constellations are areas of the sky. Although there are only 88 IAU constellations, the sky is actually divided into 89 irregularly shaped boxes as the constellation Serpens is split into two separate sections, Serpens Caput (the snake's head) to the west and Serpens Cauda (the snake's tail ...
