If luminosity increases, hypothetically, for a given galaxy, would the percentage of dark matter in that galaxy be smaller? What if the colors of the stars were to turn redder?
I was thinking if the luminosity were to increase, that would mean the percentage of the normal matters increases, thus the percentage of dark matter would decrease. But when I looked at the formula: Mass of stars: (M/L) ratio * Luminosity of stars, I was thinking the mass would be constant since the luminosities in the equation would cancel out.
