By examining the atomic carbon line from two young star systems -- 49 Ceti and Beta Pictoris -- researchers had found atomic carbon in the disk, the first time this observation has been made at sub-millimeter wavelength, hinting that the gas in debris disks is not primordial, but rather is generated from some process of collisions taking place in the debris disk.
