This is a neat result! ALMA observations show the "gravitational wiggle" in the gas in the protoplanetary disks around AB Aurigae! The presence of those wiggles would be a marker of the "top-down” pathway in planetary formation (bigger features first), instead of the bottom-up (accumulation of granules) one.

For the first time, researchers, including Naman Bajaj from the University of Arizona and Dr. Uma Gorti from the SETI Institute, have captured images of winds emanating from an aging yet still young planet-forming disk, offering vital clues on the dispersal of gas crucial for the formation of planets.
