In the early 1900’s Ejnar Hertzsprung (Danish) and Henry Norris Russell (American) found a relationship between the absolute magnitude and the surface temperature. The men were working independently.
Hertzsprung presented his information in 1905 in the form of tables, while Russell presented his observations in table form in 1913.
Today the diagram is named for both men’s work in correlating a star’s brightness and surface temperature.Why is it so important?
