Stellar Luminosity Calculator

This app calculates the luminosity of a star based on its radius and surface temperature using the Stefan-Boltzmann law.

Formula: L = 4πR²σT⁴, where:

• L = Luminosity (W)
• R = Star radius (m)
• σ = Stefan-Boltzmann constant (5.670 × 10⁻⁸ W/m²K⁴)
• T = Surface temperature (K)
