IRAS 04125+2902 (TIDYE-1) system (IMAGE) University of North Carolina at Chapel Hill Caption An artistic interpretation of the IRAS 04125+2902 (TIDYE-1) system. Young stars like this are covered in starspots—regions cooler than the surrounding stellar surface. The inner disk is depleted, leaving an intact outer disk that forms a donut-like structure around the host star. The outer disk is nearly face-on, in contrast to the edge-on planet orbit around the host star. This allows for an unobstructed view of the system. If the disk were also edge-on, it would block the planet and host star, preventing the discovery. Credit NASA/JPL-Caltech/R. Hurt, K.
