Analysis the spectrum of IC2944


I have chosen 6 random points from my graphic and calculated the eV. All the results are between 0eV and 3,51 eV which indicates that it is H because the next number in the periodic table is He (7,56eV)  


Comparison of my results with other scientists

I have found this article from Monthly Notices of the Royal Astronomical Society. The scientists who has studied the nebula IC2944 has found that is a star O-type star.

An O-type star is a hot, blue-white star of spectral type O in the Yerkes classification system employed by astronomers. They have temperatures in excess of 30,000 kelvin (K). Stars of this type have strong absorption lines of ionised helium, strong lines of other ionised elements, and hydrogen and neutral helium lines weaker than spectral type B.

His study coincides with mine. We have found hydrogen too.
