Note the Radius = R0 line through the Sun. All stars on that line have the same size as the Sun. The slope of the line occurs because luminosity varies as T4. The parallel lines, spaced 100 solar luminosity units (five magnitudes) apart are The HR diagram can be seen as both a snapshot of the state of a large collection of stars, or a generalization of the evolutionary pathways of individual stars. origin of the Hertzsprung-Russell diagram This curious fact was first noticed back in the early 1900s by two astronomers, American Henry Norris Russell and Dane Ejnar Hertzsprung. As a result, this sort of graph is called a Hertzsprung-Russell diagram, or "HR diagram" for short. Norris and Russell called the diagonal strip along which most stars fall the main sequence. The payoff: we can decode the HR diagram and learn that the main sequence is a mass sequence (and that off the main sequence things are more complicated). Main sequence stars Masses on the Main Sequence Stellar Sizes Stars in different parts of the HR Diagram are in different phases of their life cycles.

So the H-R diagram can tell us something about the size (radius) of the stars. The fact that the H-R diagrams for the nearby stars, the Pleiades star cluster, and the M3 star cluster are all different leads us to look for other differences in these groups of stars that might explain it. It turns out that the difference is the age of the stars

The Hertzsprung Russell diagram plots the Luminosity of stars against against their temperature. This gives us a lot of  Hertzsprung-Russell diagram [for Ejnar Hertzsprung and H. N. Russell], graph showing the luminosity of a star as a function of its surface temperature.

Betydelse och förklaring(ar) HR-diagram - Substantiv HR-diagram (astronomi) kortform för Hertzsprung–Russell-diagram.

The Hertzsprung–Russell diagram, abbreviated as H–R diagram, HR diagram or HRD, is a scatter plot of stars showing the relationship between the stars' absolute magnitudes or luminosities versus their stellar classifications or effective temperatures. Ett Hertzsprung–Russell-diagram, HR-diagram, är en grafisk presentation av stjärnornas absoluta ljusstyrkor eller luminositeter mot något mått på deras temperatur, spektraltyp eller färg. En stjärnas position i diagrammet avslöjar i vilken utvecklingsfas den befinner sig. One of the most useful and powerful plots in astrophysics is the Hertzsprung-Russell diagram (hereafter called the H-R diagram). It originated in 1911 when the Danish astronomer, Ejnar Hertzsprung, plotted the absolute magnitude of stars against their colour (hence effective temperature).

Classifying Stars - the Hertzsprung-Russell Diagram There are a few hundred billion stars in our galaxy, the Milky Way and billions of galaxies in the Universe. One important technique in science is to try and sort or classify things into groups and seek out trends or patterns. Astronomers do this with stars. Start studying HR Diagram.
