The dark lines denote the presence of matter other than helium. The reason the lines are dark is that the emitted radiation has been absorbed by elements present in the star.

WebHow do spectrographs help astronomers classify stars? The astronomers use the spectrographs to classify the stars on the basis of the composition of the elements present in them. The element present in them absorbs all the wavelengths of light and reflects back the wavelength which is not absorbed by the element. WebSpectrographs Spectroscopic observational techniques transform the light from an astronomical source into its components, so that we may observe the intensity of the source as a function of wavelength (or frequency, or energy, or temperature, depending on which regime of the E&M spectrum one is in and what the convention is).
