and its constancy among the four regions with available data can be reproduced by the simulations only if. More recently it has been found that color is also correlated with intrinsic brightness.1 Thus, two stars having different luminosities,. C the luminosity of stars rises to a peak at around a mass of 1 solar mass, and decreases as mass increases beyond this limit. Since more than years, Cramer Maeder uses XY and Z parameters from the Geneva photometric Amazon.com: PC system in order to estimate T eff log g and for B to A stars. Measuring the stars luminosity was more difficult.
