Abstract

Spectroscopy involves splitting light into its constituent wavelengths of light then observing the absorption and emission lines produced by the chemical elements the light is passing through or produced from. Using a spectrometer with the 14 inch Meade telescope on top of the engineering lab building at USU, stellar and planetary spectra were observed. The data collected was used to determine the chemical makeup of these celestial bodies. The spectra of the observed stars also provided information on their temperature and apparent color. The stars selected range in diameter from that of our own sun to 1000 times the sun's diameter with a few sizes in between. A correlation was made of the size of a star to its temperature, color and chemical makeup.
