The mass and chemical composition of the star are used as the inputs, and the luminosity and surface temperature are the only constraints.
en.wikipedia.org The temperatures of giant and supergiant stars of the same spectral type are somewhat different, whereas the radius and luminosity can be dramatically different.
en.wikipedia.org Adopting larger ages allows protostars to radiate the same amount of energy over a longer time, reducing their average luminosity.
en.wikipedia.org The figure to the right shows two luminosity functions for an example population of stars that is magnitude-limited.
en.wikipedia.org When one star passes in front of the other, the luminosity of the system is seen to decrease.
