Explanation:
Detailed explanation-1: -These diagrams, called the Hertzsprung-Russell or HR diagrams, plot luminosity in solar units on the Y axis and stellar temperature on the X axis, as shown below.
Detailed explanation-2: -The Hertzsprung-Russell diagram (or H-R diagram) is a graph that shows the relationship between a star’s surface temperature and brightness. (Brightness is displayed as absolute magnitude or luminosity.)
Detailed explanation-3: -The position of each dot on the diagram tells us two things about each star: its luminosity (or absolute magnitude) and its temperature. The vertical axis represents the star’s luminosity or absolute magnitude.
