HD 106906 Simulations (IMAGE) Carnegie Institution for Science Caption Two images of the HD 106906 stellar system created by Erika Nesvold and her team's simulation. The left panel shows a zoomed-in image of the ring of leftover rocky and icy planet-forming material that is rotating around the star. (The star is masked by the black circle.) The different hues represent gradients of brightness in the disk material. (Yellow is the brightest and blue the dimmest.). The right panel shows a farther-out view of the simulated system. The star is represented by the yellow circle with an arrow pointing to the exoplanet, 106906b. Nesvold's team demonstrated that the exoplanet is shaping the structure of the debris disk, which is shown by the white and blue dots encircling the star.
