Hr Diagram Sun
Hr Diagram Sun. In an H-R diagram the luminosity or energy output of a star is plotted on the vertical axis. Several of the brightest stars are identified by name.
It depends on both the radius of the star and on its surface temperature.
It is referred to as the Hertzsprung-Russell Diagram (or simply HR diagram).

It is one of the most important and widely used diagrams in astronomy, with applications that extend far beyond the purposes for which it was originally developed more than a century ago. The Hertzsprung-Russell diagram is a graph that plots the temperature of a star against its absolute magnitude or luminosity. The Hertzsprung-Russell Diagram A graph of the temperature and luminosity of stars is called the Hertzsprung-Russell Diagram (H-R Diagram), which is named after two famous astronomers.
