Hertz Russell 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 stars or spectral type against their absolute magnitude the. The hertzprung russell h r diagram is a plot of stars surface temperature or a variable thats directly tied to temperature against stars energy output or a variable directly tied to energy output.
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 stars or spectral type against their absolute magnitude the. This can be expressed as a ratio of the stars luminosity to that of the sun. Hertzsprung russell diagram ˈhɜːtssprʌŋˈrʌsəl noun a graph in which the spectral types of stars are plotted against their absolute magnitudes.
What do we mean by spectral class.
Hertzsprung russell h r diagram this diagram is called the hertzsprung russell h r diagram. Is a plot of luminosity absolute magnitude against the colour of the stars ranging from the high temperature blue white stars on the left side of the diagram to the low temperature red stars on the right side. A hertzsprung russell diagram sometimes abbreviated to hr diagram is essentially a description of the different types of stars. The hertzprung russell h r diagram is a plot of stars surface temperature or a variable thats directly tied to temperature against stars energy output or a variable directly tied to energy output.
