Measuring the color of a star is just the beginning of understanding its properties. Watch the BBC clip Spectroscopy of Stars to see how a more detailed study of the color of stars leads us to stellar spectra.
Review 17.3 The Spectra of Stars (and Brown Dwarfs) to understand how differences in temperature affect the spectra of stars and the classification system used to categorize them.
Watch the video Stars from Crash Course Astronomy, which provides a helpful summary of stellar spectroscopy and gives us a sneak peek of where this is all headed later in our unit - the HR Diagram.
