The Stefan-Boltzmann Constant is a physical constant relating the power radiated from a Black Body to its Temperature according to the Stefan-Boltzmann Law (i.e., Stefan-Boltzmann Equation, different from the Boltzmann Equation): the energy radiated by a black body is proportional to its surface and the fourth power of its temperature: j^{*} = σT^{4}
In SI units, it is: σ = 5.67036713×10^{-8} W m^{-2} K^{-4} It can be derived from the Boltzmann Constant, Planck Constant, and the speed of light. Referenced by: Stellar Radius Determination Stellar Structure |
