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 ...
Regulus is the brightest star in the constellation of Leo (right tip, below is bright Jupiter in 2004). Regulus is a multiple star system consisting of at least four stars and a substellar object. Regulus A is the dominant star, with a binary companion 177" distant that is thought to be physically related.
Beta Lyrae Aa is a semidetached binary system made up of a stellar class B6-8 primary star and a secondary that is probably also a B-type star. The fainter, less massive star in the system was once the more massive member of the pair, which caused it to evolve away from the main sequence first and become a giant star .

A multiple star system consists of two or more stars that appear from Earth to be close to one another in the sky. [dubious – discuss] This may result from the stars actually being physically close and gravitationally bound to each other, in which case it is a physical multiple star, or this closeness may be merely apparent, in which case it is an optical multiple star [a] Physical multiple ...
Kolob is a star or planet described in the Book of Abraham, a sacred text in many traditions of the Latter Day Saint movement. Kolob is also mentioned in a Latter-day Saint hymn. The Book of Abraham refers to Kolob as a "star", however, it also refers to several planets as stars, and Kolob is commonly viewed as a planet by Latter Day Saints today.
ο Leonis (Latinised to Omicron Leonis) is the star's Bayer designation.The designations of the two constituents as Omicron Leonis A and B, and those of A's components—Omicron Leonis Aa and Ab—derive from the convention used by the Washington Multiplicity Catalog (WMC) for multiple star systems, and adopted by the International Astronomical Union (IAU).
