Hertzsprung-Russell Diagram Lab

The NAAP HR Diagram Lab explores the Hertzsprung-Russell diagram and those areas necessary to understand the diagram such as (but not limited to) the different kinds of spectrum, spectral classification, and luminosity class. In short, this module provides a fairly in-depth tutorial in reading HR diagrams.

First time users of NAAP materials should read the NAAP Labs – General Overview page.

Details and resources for this lab – including demonstration guides, in-class worksheets, and technical documents – can be found on the instructor's page. Some resources are not available for all modules.
