The Hertzsprung-Russell diagram (or HR diagram) is constructed in logarithmic coordinates.

In this graphic construction, each star is a point marked on the. 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. In previous activities with the star life cycle.

If you sit with the interactive and watch the stars' movement on the HR diagram, you get a real feel for a basic fact of stellar evolution - low mass stars take a long .

This interactive lab explores the Hertzsprung-Russell Diagram in areas of spectrum, classification, luminosity, and temperature. The simulator plots stars.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. 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.

Classifying Stars - the Hertzsprung-Russell Diagram There are a few hundred billion stars in our galaxy, the Milky Way and billions of galaxies in the Universe. One important technique in science is to try and sort or classify things into groups and seek out trends or patterns.

Astronomers do this with stars. 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.
