## Mass-Luminosity Relation
For main-sequence stars, luminosity increases steeply with mass:
**L / L_sun ≈ (M / M_sun)^3.5**
This is an empirical fit. The exponent varies from about 2.3 for very low-mass stars to about 4 for massive stars, with 3.5 being a good average.
A 10 M_sun star is ~3162 times as luminous as the Sun.

Exemple Résolu
A 2 solar-mass star.
- L/L_sun = 2^3.5
- = 2^3 × 2^0.5 = 8 × 1.414 = 11.31
- About 11.3 times the Sun's luminosity.
