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 (as opposed to merely the visible light), scaled like an absolute magnitude. (Without the word "absolute", there is some ambiguity: it could be used to mean apparent bolometric magnitude.)

It is equivalent to luminosity, but using a logarithmic scale. It is generally approximated from observed quantities by determining the absolute magnitude, then applying a bolometric correction.
