WebSome HR diagrams include the color of stars as they can be seen through filters on spectrophotometers. This is also a "ratio scale." So how do you read the HR diagram? Well, let’s look at some basic regions on it. A … WebThe Hertzsprung-Russell (H-R) diagram is an analog to the periodic table of the elements. It was discovered that when the absolute magnitude (M V) – intrinsic brightness – of stars is plotted against their surface temperature (stellar classification) the stars are not randomly distributed on the graph but are mostly restricted to a few well-defined regions.

WebAn actual HR Diagram is provided in the upper right panel with an active location indicated by a red x. This active location can be dragged around the diagram. The options panel allows you to control the variables plotted on the x-axis: (temperature, B- V, or spectral type) and those plotted on the y-axis (luminosity or absolute magnitude). WebThe various forms of the HR diagram come from the different manner in which stars may be studied.
