Stars get their names assigned by random at the moment when the cluster is generated, following some rules according to the star types.

Main-Sequence Stars, White Dwarves and Giant Stars may get their names from one of the two fixed lists, one for the Generic Stars and White Dwarves and another for the Giants. For the most of these names there is a star existing in the real world, but the in-game star does not have to correspond its real-life counterpart in the spectral class or other paramters.

Main-Sequence Stars, White Dwarves and Giant Stars may also get their names according to the Bayer designation, i.e. a Greek letter or a number followed by the Latin name of the constellation in the genitive case.

Giants can also get their names formed from a literal prefix followed by a decimal code. The prefix generally corresponds to the one used in an existing star catalogue.

Neutron Stars and Black Holes are always named with the literal prefix and the decimal code.

Below, the ITALICIZED letters are variables. See notes for clarifications.

Main-Sequence Stars & White Dwarves (fixed names)

425 names.

  1. ↑ 1.0 1.1 Alphard and Cor Hydrae are the alternative names of the same star.
  2. ↑ Binary Star
  3. ↑ 3.0 3.1 One of the names of the stars otherwise known as Epsilon Aquilae and Zeta Aquilae.
  4. ↑ One of the names of the stars otherwise known as Beta Ceti and Iota Ceti.
  5. ↑ Giedi Prime is a fictional planet from Frank Herbert's sci-fi saga Dune.
  6. ↑ 6.0 6.1 Izar and Pulcherrima are the alternative names of the same star
  7. ↑ 7.0 7.1 May refer to one of the following real world stars: γ Lib, η Lib, ν Lib, σ Lib or υ Lib.

Bayer Designations

All the 88 constellations below exist in the real world.

X may be one of [Alpha, Beta, Gamma, Delta, Epsilon, Zeta, Eta, Theta, Iota, Kappa, Lambda] for constellation names less than 10 letters or one of [α, β, γ, δ, ε, ζ, η, θ, ι, κ, λ] for the longer names.

X may also be an arabic number between 27 and 74.

For the Giant Stars, X may only be the number between 145 and 180.

Giant Stars (fixed names)

60 names.

All these stars exist in reality.

Giant Stars (catalogue names)

7 name templates.
