Stellar Types & the H-R Diagram
This sub-section of the Stars section of the site discusses how stars are classified as well as a few special types of stars and star systems.
The first part, Spectral Classification, is how stars were initially categorized by color and their spectra.
The second part, the Hertzsprung-Russell Diagram, is one of the most important ways to display information about stars. It is also sometimes referred to as a "Color-Magnitude Diagram."
The third page in this sub-section discusses binary star systems.
The fourth talks about the five main types of variable stars - T Tauri, Cepheid, RR Lyrae, Mira, and Cataclysmic.
Future pages may be added to this section of the site by your request.
