Researchers have developed computer simulation designs for a better understanding of the effects. The simulations were generated and run on Discover supercomputer cluster at the NASA Center for Climate Simulation at Goddard. Wladimir Lyra, a professor of astronomy at California State University, Northridge and Marc Kuchner, an astrophysicist at NASA's Goddard Space Flight Center in Greenbelt, Maryland, had earlier suggested that PeI could explain the narrow rings seen in some disks in 2013. The model was, however, directly observed in 2016 during Alexander Richert's study. It was found that some discs would have arcs or incomplete rings similar to earlier predictions.
