absolute magnitude:

in astronomy, measure of the brightness of a star or other celestial object. The stars cataloged by Ptolemy (2d cent. A.D.), all visible with the unaided eye, were ranked on a brightness scale such that the brightest stars were of 1st magnitude and the dimmest stars

absolute magnitude

[′ab·sə‚lüt ′mag·nə·tüd]
(astrophysics)
A measure of the brightness of a star equal to the magnitude the star would have at a distance of 10 parsecs from the observer.
The stellar magnitude any meteor would have if placed in the observer's zenith at a height of 100 kilometers.
(mathematics)

(82-84) In this analysis, one needs to introduce the Eddington ratio [lambda], the bolometric luminosity divided by the Eddington luminosity, given as [L.sub.Edd] = 1.25 x [10.sup.38](M/M0) erg [s.sup.-1] for a black hole mass of M.
The spectral features observed at the visual maximum suggest that [T.sub.eff] became ~8000-9000 K that is consistent with an assumption of the bolometric luminosity constancy during the eruption, as is typically observed in LBVs.

According to (A.2) and (A.3), the resulting relationship of typical PRT versus bolometric luminosity becomes
