In this artist's interpretation, baby planets forming around the young star HD 142527 are pulling streams of gas inward toward them as they grow. Much of the gas then overshoots the planets and continues inward to the portion of the disk close to the star, where it can eventually fall onto the star itself. HD 142527 is notable for its protoplanetary disk and its discovery has has helped refine models of planet formation. The studies have shown eddies and vortex structures forming in the nebulae under the influence of two large planets. The star is important as it allows Astronomers to observe the accretion process in planetary formation.
