Lesson: Hertzsprung–Russell Diagrams Physics

Start Practising

In this lesson, we will learn how to interpret Hertzsprung–Russell diagrams and identify types of stars based on their position on the diagram.

Lesson Plan

Students will be able to

interpret Hertzsprung–Russell diagrams shown either in terms of absolute magnitude and spectral class or in terms of luminosity (in units of solar luminosity) and surface temperature,
identify the main sequence on a Hertzsprung–Russell diagram,
identify where red giant stars appear on a Hertzsprung–Russell diagram,
locate the likely position of a star on a Hertzsprung–Russell diagram given its absolute magnitude, luminosity, or type and its spectral class or surface temperature.
