Fig7_10 Stellar mass luminosity relation

Fig. 7.10 . An empirical mass-luminosity relation for main-sequence stars of absolute luminosity, L, in units of the solar luminosity, L§, and mass, M, in units of the Sunís mass, M§. The straight line corresponds to luminosity that is proportional to the fourth power of the mass. The English astronomer Arthur Eddington (1882-1944) proposed a theoretical explanation for this relation in 1924.
