Hertzsprung-Russell (HR) Diagram The diagram below shows an example of an Hertzsprung-Russell (H-R) diagram. The first such diagram was plotted by Ejnar Hertzspung in 1911, and (independently) by Henry Norris Russell in 1913. It is a "two... 

The Hertzsrung-Russell Diagram (HR Diagram) as related to Stellar Radius and Temperature This page uses Java Script for the Calculations written by Larry Bogan The HR Diagrams plots stellar brightness versus surface temperature Luminosity vs. Surface 

In a Hertzsprung-Russell diagram, each star is represented by a dot. One uses data from lots of stars, so there are lots of dots. The position of each dot on the diagram corresponds to the star's luminosity and its temperature

HR Diagram I drew the HR diagram, explained the axes and main sequence. I then explained how you can estimate the radius of a star by assuming it behaves like a blackbody and reading the luminosity and temperature off the HR diagram. After I had
