The H-R Diagram

The H-R Diagram. In 1913, the American astronomer Henry Russel plotted the luminosities of stars versus their spectra class (related to the temperature). Similar to work done in 1911 by Danish astronomer Ejnar Hertzsprung They found that the luminosities and temperatures of star are related
