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.More simply, it plots each star on a graph plotting the star's brightness against its temperature (color). Classifying Stars The Hertzsprung Russell Diagram 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. Color Designation and the Hertzsprung Russell Diagram The Hertzsprung Russell diagram, or simply the H R diagram, plots star color along the horizontal axis and luminosity along the vertical axis. To make the chart fit on a single page, we actually plot the log 10 of the luminosity. Color Magnitude and Color Color plots CoolWiki Color color plots can be used to separate objects of different types, such as distinguishing galaxies from stars. The plot on the right comes from Fig.2 from Fan et al. 2001, AJ, 122, 2833, and was used to show how the quasars (lower right) are different than brown dwarfs (top) and more boring objects (cluster of points). The Hertzsprung Russell (HR) 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. worksheet stars and hr diagram SC TRITON Science 3.

Introduction to the Hertzsprung Russell Diagram 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).
