In time, astronomers began to turn their attention to the myriad other stars available for study. The achievements of Joseph Fraunhofer provided the quantitative basis for spectroscopy. The above spectrum was created at the McMath-Pierce Solar Observatory and shows, first off, that although our yellow-appearing Sun emits light of nearly every color , it does indeed appear brightest in yellow-green light. Spectroscopy of the Sun in the 10-12 μm infrared window has revealed the presence of emission lines due to high-n transitions in neutral Magnesium and Aluminum, as well as rotational transitions in several vibrational states of the OH radical. Kirchhoff realized that the Sun was hot and gaseous. electronic finderscope, Comet We use a high resolution and high signal-to-noise ratio spectrum of the Sun from the Kitt Peak telescope as a starting point to compile the iron line list.
