Do you ever ponder the mass-luminosity relationship for main sequence stars?

Q = log₁₀ (M/M☉) Mass-Luminosity Relationship. For M/M☉ ≤ 1.0, log(L/L☉) = −3.9428277 Q⁴ − 5.5932802 Q³ + 0.52340218 Q² + 5.04234542 Q + 0.0011365 Mass-Temperature Relationship. For M/M☉ ≤ 1.0, log(T/5777K) = −0.3029217 Q⁴ − 0.1692644 Q³ + 0.54817448 Q² + 0.72509654 Q + 0.00069854 Star's... show more Q = log₁₀ (M/M☉)
