What is a star's emission spectrum? It is the same as the HR diagram and gives the same information. It is the fingerprint of all of the colors of light emitted by a star. It is a graph of all the pollution given off by a star. It is a graph of the starâs solar flares.
Light from Stars. Because stars emit light with different wavelengths, they have different colors. Stars do not just emit one wavelength of electromagnetic radiation, but a range of wavelengths. If you look at the amount of light a star gives off at different wavelengths, you would get a graph like the one shown to the right. The wavelength at which a star emits the most light is called the star's peak wavelength.
