Rather, Hertzsprung-Russell diagrams plot each star on a graph measuring the star's brightness versus its temperature. Hertzsprung-Russell diagrams are also called H-R diagrams or HRDs.
The Hertzsprung-Russell Diagram. Origin of the Hertzsprung-Russell Diagram. Many scientific discoveries are made first theoretically and then proven to be correct, or nearly so, in the laboratory. That was not the case however, for the Hertzsprung-Russell diagram. A significant tool to aid in the understanding of stellar evolution, the H-R diagram was discovered independently by two astronomers in 1912 using observational comparisons
The Hertzsprung-Russell diagram (HR diagram) is one of the most important tools in the study of stellar evolution. The giant branch is also well populated and there are many white dwarfs.
Scientists may also use the diagram to obtain a rough measure of the distance of a star cluster from Earth.
Richard Brevard Russell Jr. (November 2, 1897 – January 21, 1971) was an American politician. A member of the Democratic Party, he served as the 66th Governor of Georgia from 1931 to 1933 before serving in the United States Senate for almost 40 years, from 1933 to 1971. Russell was a founder and leader of the conservative coalition that dominated Congress from 1937 to 1963, and at his death was the most senior member of the Senate.
The Hertzsprung-Russell diagram was developed by astronomers Ejnar Hertzsprung and Henry Norris Russell back in 1910. Another version of the diagram plots the effective surface temperature of the star on one axis and the luminosity of the star on the other.
