Spectra of Each of the Primary Spectral Classes
12.5" Newtonian and Star Analyzer
Uploaded 10/22/12
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.
