Splet9. 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. SpletThe relation between the mass of a star and its luminosity on the main sequence (mass–luminosity relation, hereafter MLR) is a fundamental law that is used in various fields of astrophysics. For single objects, the MLR allows astronomers to convert a relatively easily observed quantity, luminosity, to a more fundamental characteristic, mass ... purgatory closing daySpletThe Mass-Luminosity Relation Now that we have measurements of the characteristics of many different types of stars, we can search for relationships among the characteristics.
