The mass-luminosity relation works for
Spletmass-luminosity relation, in astronomy, law stating that the luminosity of a star is proportional to some power of the mass of the star. More massive stars are in general more luminous. For stars on the main sequence of the Hertzsprung-Russell diagram, it is found empirically that the luminosity varies as the 3.5 power of the mass. Splet01. sep. 2004 · Search for other works by this author on: Oxford Academic. ... The mass–luminosity relation is then calculated by setting the luminosity L of a galaxy hosted in a halo of mass M to be such that the number of galaxies with luminosity greater than L equals the number of haloes plus subhaloes with mass greater than M: 9.

A binary star system, which is quite common, will allow us to determine mass with great accuracy, using Kepler's Third Law of Planetary Motion which is as follows: T 2 r 3 = 4 π 2 G M s u m. Using the orbital period, T, we can determine the acceleration and affect that stars have on one another to determine mass.
