A sample laser frequency comb spectrum In this laser frequency comb, colorized for illustrative purposes, the solid lines are the star spectrum and the dots are the artificial laser spectrum. The dark gaps in the star spectrum represent different chemical elements in the starlight. Long-term star observations can be calibrated using the artificial spectrum to reveal if the star is wobbling due to the presence of an exoplanet.
