Hess diagram

(diagram relating effective temperature to luminosity)

A Hess diagram is a graph showing the density of occurrence of stars over the same axes as H-R diagrams: effective temperature versus luminosity. Richard Hess originated the concept in 1924, using lines like those of a typical drawn topographic map. Currently, it is common to use colors or grayscale to indicate the densities. The term Hess diagram is occasionally used to indicate the same style of density plot of other types of densities.
