- 1Input absolute magnitude or temperature/radius
- 2Apply Stefan-Boltzmann law or magnitude conversion
- 3Results show luminosity in solar units
Worked Examples
Ievade
Sun = 1 L☉, Sirius ≈ 26 L☉
Rezultāts
Sirius 26 times more luminous
Despite similar temperature
Common Mistakes to Avoid
- ✕Confusing luminosity with apparent brightness (distance matters)
- ✕Using wrong reference star
Frequently Asked Questions
How does luminosity relate to size?
L ∝ R² × T⁴; doubling radius increases luminosity 4×.
