This effect of an evolving hr diagram with age becomes a powerful test of our stellar evolution models. Then an theoretical hr diagram can be built at each timestep. The hertzsprung russell diagram is one of the most important tools in the study of stellar evolutiondeveloped independently in the early 1900s by ejnar hertzsprung and henry norris russell it plots the temperature of stars against their luminosity the theoretical hr diagram or the colour of stars or spectral type against their absolute magnitude the observational hr.
