Luminosity Calculator
Calculate the luminosity of a star using its radius and surface temperature.
Formula:
Luminosity (Stefan-Boltzmann Law):
L = 4 × π × R² × σ × T⁴
Where:
L = luminosity (W)
R = radius of the star (m)
T = surface temperature (K)
σ = Stefan-Boltzmann constant = 5.670374419 × 10⁻⁸ W·m⁻²·K⁻⁴
