Since then, variations of the Stefan Law is widely used to determine some basic properties of a star, like:
- Star Radius
- Star Luminosity
- Star Surface temperature
To calculate any given star Luminosity, Stefan's law is expressed as:
L = 4 π R2 σ Τ 4
L: Luminosity (in Watts)
R: Star radius
T: Star's surface temperature.
This is a variation of the original Stefan's formula, widely used to calculate any star temperature by finding the absolute luminosity
based in relative comparations with proper references:
j = T4
where j is the Iradiance or Flux Density (Watt/m^2), which is estimated by comparisons with references (like our Sun's Irradiance).
