Web23 de mai. de 2024 · Resources. A Hertzsprung-Russell diagram, or HR diagram, is a graph of stellar temperatures (plotted on the horizontal axis) and luminosities or brightnesses (plotted on the vertical axis). HR diagrams are valuable because they reveal important information about the stars plotted on them. After constructing an HR diagram … Web29 de out. de 2024 · The HR diagram is really easy to understand if you are able to interpret what each axis means. The horizontal axis measures the surface temperature of the star in Kelvin. The stars that are over on the right are 3000 Kelvin and are much cooler and redder in color than the stars on the left. This diagram goes up to 25,000 Kelvin, but the surface ...
