Domain-specific

• A-Type Main-Sequence Star
  • Morgan and Keenan describe spectral classification as an empirical system organized by standard spectra rather than a direct inversion from one measured physical quantity.
• B-type Main-Sequence Star
  • In ordinary stellar-astrophysical use, this joint classification identifies a hot, blue-to-blue-white, core-hydrogen-burning star.

    This sourceAuthoritative review of the MK system and its standard-star practice.
