The NAAP HR Diagram Lab explores the Hertzsprung-Russell diagram and those areas necessary to understand the diagram such as (but not limited to) the different kinds of …

Hertzsprung-Russell diagram, in astronomy, graph in which the absolute magnitudes (intrinsic brightness) of stars are plotted against their spectral types (temperatures).

The H-R diagram is a scatter graph of stars – a plot of stellar absolute magnitude or luminosity versus surface temperature or stellar classification. Stages of stellar evolution occupy specific …

This Hertzsprung-Russell diagram shows a group of stars in various stages of their evolution. By far the most prominent feature is the main sequence, which runs from the upper left (hot, …

Astronomers use the Hertzsprung-Russell diagram to trace the evolutionary stage of a star. The Hertzsprung diagram where the evolution of sun-like stars is traced.

The classical HR diagram, first constructed in 1914 by Henry Norris Russell (to which was added the work of Ejnar Hertzsprung), is a plot of absolute visual magnitude against spectral class. …

During roughly the same time period, two astronomers created similar plots while investigating the relationships among the properties of stars, and today we refer to these plots as " Hertzsprung …
