WebJan 29, 2024 · L = 4 π R 2 σ T 4 L ⊙. Because we're using the Stefan-Boltzmann equation, instead of the distance to the star, we have to use its radius. Vega's radius is 2.362 R ⊙, which is 1.64 × 10 9 meters. Its surface temperature is 9,600 K. Plugging in those numbers yields a luminosity of: L = 42.7 L ⊙.
