WebThis diagram is called the Hertzsprung-Russell (H-R) diagram. It shows stars according to their temperature and brightness. The stars on the diagonal line are in the main sequence stage of... WebSummary The Hertzsprung-Russell diagram (or HR diagram) is constructed in logarithmic coordinates. In this graphic construction, each star is a point marked on the ordinate by its brightness (luminosity or absolute magnitude) and on the abscissa by its spectral type (or surface temperature).
