bolometric stellar magnitude
1Stellar classification — In astronomy, stellar classification is a classification of stars based on their spectral characteristics. The spectral class of a star is a designated class of a star describing the ionization of its chromosphere, what atomic excitations are… …
2Absolute magnitude — In astronomy, absolute magnitude (also known as absolute visual magnitude) is the apparent magnitude an object would have if it were at a standard luminosity distance (10 parsecs, 1 AU, or 100 km depending on object type) away from the observer,… …
3Supergiant — Supergiants are among the most massive stars. In the Hertzsprung Russell diagram they occupy the top region of the diagram. In the Yerkes spectral classification supergiants are class Ia (most luminous supergiants) or Ib (less luminous… …
