The mass-luminosity relation works for

The mass/luminosity relationship can also be used to determine the lifetime of stars by noting that lifetime is approximately proportional to M/L although one finds that more massive stars have shorter lifetimes than that which the M/L relationship predicts. A more sophisticated calculation factors in a star's loss … Prikaži več In astrophysics, the mass–luminosity relation is an equation giving the relationship between a star's mass and its luminosity, first noted by Jakob Karl Ernst Halm. The relationship is represented by the equation: Prikaži več Deriving a theoretically exact mass/luminosity relation requires finding the energy generation equation and building a … Prikaži več To the first approximation, stars are black body radiators with a surface area of 4πR .
