Hr Diagram Luminosity astro unl edu naap hr hr htmlThe 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 spectrum spectral classification and luminosity class Hr Diagram Luminosity Russell diagramThe Hertzsprung Russell diagram abbreviated 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 measuring the star s brightness against its temperature color
