If you are interested in learning more about measuring stellar properties, I recommend:
- The Doppler Effect and Sonic Booms.
- From the "Practical Uses of Math and Science" is a description of an in-class activity on trigonometric parallax.
- Jim Kaler's website on STARS and the Star of the Week are an excellent source of information on all aspects of stars, including topics like color, spectral types, the HR diagram, and others.
- At the Sloan Digital Sky Survey SkyServer website, they have a basic and advanced lab exercise on measuring the colors of stars. They also have a basic lab exercise and an advanced lab exercise on classifying stars into spectral types.
- TERC has available as a sample activity an excellent HR diagram activity for classroom use. Unfortunately, after years of availability, the website has been taken down. I've posted the files in Canvas if you want to look at it, because I consider it to be one of the absolute best activities for doing HR diagrams with students.
