Stellar Radius Calculator

Calculate the radius of a star based on its luminosity and surface temperature.

Formula:

Stellar Radius (from Stefan-Boltzmann Law):

R = √(L / (4 × π × σ × T⁴))

Where:
R = radius of the star (m)
L = luminosity (W)
T = surface temperature (K)
σ = Stefan-Boltzmann constant = 5.670374419 × 10⁻⁸ W·m⁻²·K⁻⁴
