Spectra of Each of the Primary Spectral Classes

Here
            is the results of my first spectroscopic project, a collection
            arranged in sequence of a representitive star from each classical
            class of type of star, from O to M. Underneath, the original
            data is provided in two formats. The first is an instrument calibrated
            response curve on the star used in the class type, followed by
            a continuum normalized version to best illustrate the spectral
            lines. A DMK51 from Imaging Source was used for this project,
            which has an extended IR response as you can see from the Telluric
            band on the right of each spectrum as a dark thick band, which
            represents Earths atmospheric Oxygen superimposed on the stars
            spectra.
