Hr Star Hertzsprung Russell Diagram. 17 rows hertzsprung and russell were two astronomers who independently of each other. This diagram is called the hertzsprung russell h r diagram.
Developed independently in the early 1900s by ejnar hertzsprung and henry norris russell it plots the temperature of stars against their luminosity the theoretical hr diagram or the colour of. If you have more than one star that looks alike in diameter and color group them in a small area. April 15th 2019 hertzsprung russell diagram commonly referred to as h r diagram the h r diagram was named after its discov erers ejnar hertzsprung and henry norris russell as described in a later section each point on the h r diagram represents the state of a star characterized by the its temperature and luminosi ty.
It shows stars according to their temperature and brightness.
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. This diagram is called the hertzsprung russell h r diagram. The hertzsprung russell hr diagram is a plot of luminosity total power output against surface temperature both on log scales. Created around 1910 by ejnar hertzsprung and henry norris russell the diagram.
