Each IAU constellation has an official three-letter abbreviation based on the genitive form of the constellation name.

Therefore, Carina has the α, β, and ε, Vela has γ and δ, Puppis has ζ, and so on. [3] In 1844, John Herschel proposed complete dividing Argo Navis in accordance with Lacaille's divisions. [4] However, the constellation continued to be used into the 20th century, and officially received a three-letter designation alongside its divisions in ...

Variable stars that do not have Bayer designations are assigned designations in a variable star scheme that superficially extends the Bayer scheme with uppercase Latin letters followed by constellation names, starting with single letters R to Z, and proceeding to pairs of letters. Such designations mark them as variable stars.
