Astronomy 1010 Final HW One of the most important earlier steps in understanding stars was to group them into classes called spectral types that could offer clues as to why they are different from one another. Shown here are spectra of some main-sequence stars. Before stars were very well understood, they were classified into an order that was based on the relative strength of hydrogen absorption lines, marked by arrows the image shown. Look at the spectra for stars of different spectral ...
