Bolometric Magnitude

(Mbol, Mbol, Absolute Bolometric Magnitude)
(absolute magnitude of all wavelengths)

Bolometric Magnitude (or Absolute Bolometric Magnitude, Mbol or Mbol) is a Magnitude-style (logarithmic) measurement of all a star's emitted Electromagnetic Radiation (EMR), scaled like Absolute Magnitude (M). (Without the word "Absolute", there is some ambiguity: it could be used to mean apparent bolometric magnitude.)

It is equivalent to Luminosity (L). It is generally approximated from observed quantities by determining the absolute magnitude, then applying a Bolometric Correction.
