R and boltzmann constant

WebbThe relationship between these is known as the Stefan-Boltzmann Law, which states: The total energy emitted by a black body per unit area per second is proportional to the fourth power of the absolute temperature of the body. It is equal to: L = 4πr 2 σT 4. Where: L = luminosity of the star (W) r = radius of the star (m) σ = the Stefan ...
