WebThe Hertzsprung-Russell (HR) diagram is a plot of luminosity (total power output) against surface temperature, both on log scales. Since neither luminosity nor surface temperature is a directly observed quantity, real plots tend to use observable quantities that are related to WebThe H-R Diagram The Hertzpsrung-Russell (H-R) diagram is a way of categorizing properties of all stars in the sky, including the Sun. The surface temperature, color, luminosity, and radius of stars can all be deduced from their location on the H-R diagram.

WebKey Concepts and Summary. The Hertzsprung–Russell diagram, or H–R diagram, is a plot of stellar luminosity against surface temperature. Most stars lie on the main sequence, which extends diagonally across the H–R diagram from high temperature and high luminosity to low temperature and low luminosity. WebThe basic H-R diagram is a temperature vs. luminosity graph. The temperature may be replaced or supplemented with spectral class (or color index as noted earlier). The main spectral classes in order from hottest to coolest are O, B, A, F, G, K, and M. These classes have particular colors. WebHertzsprung-Russell Diagrams.
