# Interactive Hertzsprung Russell Diagram  This interactive lab explores the Hertzsprung-Russell Diagram in areas of spectrum, classification, luminosity, and temperature. The simulator plots stars. OK, so now you're fairly good at reading the diagram. Let's look at why we called it a type of "family portrait" for stars.

## H R Diagram Online Activity

In previous activities with the star life cycle. H R Diagram Online Activity NAME: schematron.org schematron.org PERIOD: “Hertzsprung-Russell Diagram” page: * Read the first. This is a simple activity to help students understand stellar spectra and luminosity . Students drag a 'generic' star around a Hertzsprung-Russell Diagram and the. 1 10 Sun M a i n S e q u e n c e Luminosity (L Solar).The Hertzsprung-Russell (HR) Diagram is commonly viewed by students as simply another graph to make or even worse, simply another graph to observe and memorize. The day that my students create and interpret the Hertzsprung-Russell Diagram is one of my absolute favorite days of the year. H-R Diagram A collection of stars visible from Earth can be arranged and classified based on their color, temperature, luminosity, radius, and mass. This can be done using one or two-dimensional plots, including a Hertzsprung-Russell diagram of luminosity vs. temperature. javaHRD - An interactive Hertzsprung-Russell Diagram. A Java-applet has been developed to display tracks of evolution of stars as they are given in a Hertzsprung-Russell Diagram (HRD). This form of display is especially useful for beginners in astronomy. A collection of stars visible from Earth can be arranged and classified based on their color, temperature, luminosity, radius, and mass. This can be done using one or two-dimensional plots, including a Hertzsprung-Russell diagram of luminosity vs. temperature. The Hertzsprung–Russell diagram, abbreviated as 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 schematron.org simply, it plots each star on a graph plotting the star's brightness against its temperature (color).Hertzsprung-Russell Diagram Explorer - Hertzsprung-Russell Diagram - NAAPHertzsprung-Russell Diagram - NAAP
