This seems like it would be fairly complex as any material that is not in the suns would absorb photons and convert part of that energy over to kenetic energy giving a false value for actual luminosity from the stars themselves.
Galaxies appear to be very different from one another, is it simply assumed that most galaxies have similar material properties to make the numbers easier to calculate for?
And finally what is the formula for doing calculations of luminosity vs galaxy mass?
