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).

WebDec 14, 2024 · Another difference would just be the number of stars. A typical globular cluster might have > 10 5 stars, whereas a typical open cluster might have more like ∼ 10 3. This means the various features in the HR diagram are much better delineated in a globular cluster - the turn-off, a red giant branch and a horizontal branch. WebOct 22, 2024 · 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 of a Hertzsprung-Russell diagram shows the luminosity or brightness of the stars, as if they were all measured from the same distance. Another term for this is absolute magnitude. The brighter a star is, the higher its plot will be on this chart.
WebThe fundamental tool for presentation of the diversity of stellar types and for understanding the interrelations between the different kinds of stars is the Hertzsprung‐Russell Diagram (abbreviated HR diagram or HRD), a plot of stellar luminosity or absolute magnitude versus spectral type, stellar surface temperature, or stellar color.
