WebHertzsprung Russell diagram. The Herzsprung Russell diagram plots temperature vs. luminosity for stars. Assuming a star lies on the main sequence, the H-R diagram can be used to calculate it distance, using the spectroscopic parallax method. In 1911, a Danish astronomer named Ejnar Hertzsprung plotted the absolute magnitude against color for a ... WebSuch a plot is frequently called the Hertzsprung–Russell diagram, abbreviated H–R diagram. It is one of the most important and widely used diagrams in astronomy, with applications that extend far beyond the purposes for which it was originally developed …
