WebOct 8, 2024 · The luminosity of a star is related to its radius by the equation L = 4πR2σT4, where L is the luminosity, R is the radius, σ is the Stefan-Boltzmann constant, and T is the surface temperature of the star. This means that, for a given luminosity, a star with a higher surface temperature will have a smaller radius. WebThe luminosity of a star is given by the equation. L = 4 p R 2 s T 4, Where L is the luminosity in Watts, R is the radius in meters, s is the Stefan-Boltzmann constant. (5.67 x 10 -8 Wm -2 … thai massage bacup
