Stellar luminosity is total energy radiated per unit time. Combined with temperature and size, it determines star classification.

  1. 1Input absolute magnitude or temperature/radius
  2. 2Apply Stefan-Boltzmann law or magnitude conversion
  3. 3Results show luminosity in solar units

ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ

ଇନପୁଟ୍
Sun = 1 L☉, Sirius ≈ 26 L☉
ଫଳ
Sirius 26 times more luminous
Despite similar temperature

ଏଡ଼ାଇବା ଯୋଗ୍ୟ ସାଧାରଣ ଭୁଲ

  • Confusing luminosity with apparent brightness (distance matters)
  • Using wrong reference star

How does luminosity relate to size?

L ∝ R² × T⁴; doubling radius increases luminosity 4×.
