The external galaxies show an extremely large range in their total luminosities.

The total infrared luminosity reaches almost a trillion times of that the Sun's.
[41] The luminosity (L) of the star is roughly proportional to the total mass (M) as the following power law:
We find that, for optically thick disks, CO inner radii are strongly correlated with the total system luminosity (stellar plus accretion), and consistent with the dust sublimation radius.
We find that, for optically thick disks, CO inner radii are strongly correlated with the total system luminosity (stell... ▽ More We present an analysis of CO emission lines from a sample of T Tauri, Herbig Ae / Be, and transitional disks with known inclinations, in order to study the structure of inner disk molecular gas.
Even though most of the visible radiation is concentrated in a few discrete emission lines, the total apparent brightness of the brightest is the equivalent of tens of thousands of solar luminosities.
On January 13, 2003, a team of astronomers (including Ralf - Dieter Scholz, Mark McCaughrean, Nicolas Lodieu, and Bjoern Kuhlbrodt) announced the discovery of a brown dwarf companion «b» — now re-designated «ba» — to this nearby star with a total (bolometric) luminosity of just 0.002 percent that of the Sun (ESO and AIP joint press release and API press release in German — more below).
If this is the case, it would explain both the low value of the total bolometric flare energy (as the absolute luminosity of the superflare stars and thus the total bolometric flare energy would be larger) and the S index (as the light entering the fibre would likely be contaminated and the observed emission in the H and K lines would therefore be relatively small).
People here, including Muscheler, might have missed the point that according to instrumental total solar irradiance (TSI) measurements, solar luminosity increased from 1980 to 2000 and decreased afterword, and it was likely even lower during the 1970s.
