Stars On The Hr Diagram. The white dwarfs and red giants are different classes of stars that the h r diagram helps us to identify. In an h r diagram the luminosity or energy output of a star is plotted on the vertical axis.
In an h r diagram the luminosity or energy output of a star is plotted on the vertical axis. The hertzsprung russell diagram hr diagram is one of the most important tools in the study of stellar evolution. Determining the sizes of stars using the h r diagram exercise in this exercise you are going to use an hertzsprung russell diagram to determine the luminosity and temperature of stars.
Astronomers also use the historical concept of magnitude as a measure of a stars luminosity.
You will be using table 1 and table 2 to plot the 20 nearest and 20 brightest stars on the attached hr diagram. It gives the relationship between the luminosity of stars against their type and temperature. Hertzsprung russell h r diagram this diagram is called the hertzsprung russell h r diagram. 1 main sequence the long diagonal band.
