sci.stellar-evolution-main-sequence Calculator
Calculates main sequence stellar luminosity from mass using the empirical mass-luminosity relation: L ∝ M^3.5 for mid-range stars. A 2 M☉ star is ~11× more luminous than the Sun — its main sequence lifetime is ~11× shorter, burning out in ~1 Gyr.
Inputs
Mass Solar Masses
Total mass (kg). Distinct from weight — weight = mass × gravity. Mass is constant; weight varies with location.
Results
luminosity (L☉)
Total power output of a star or light source in watts or solar luminosities. Relates to absolute magnitude.
radius (R☉)
The computed radius -- half the diameter.
effective temperature (K)
The value at the specified point or condition.
main sequence lifetime (Myr)
The computed duration or time value.
mass-luminosity: L ∝ M⁴
Total power output of a star or light source in watts or solar luminosities. Relates to absolute magnitude.
10 M☉ star
