While recent observations have found such disks surrounding the baby - twin stars, named «circumbinary disks», those observations could not image the structures and gas motions of the disks to feed materials to the binary, because of the insufficient imaging resolution and sensitivity.

Astronomers have used the National Science Foundation's Very Long Baseline Array radio telescope to make the first - ever time - lapse movie showing details of gas motions around a star other than our Sun. (public.nrao.edu)
The inter-arm regions also exhibit a falling gas motion toward the central baby twin stars, namely, the ongoing feeding process of the materials to the baby twin stars. (alma-telescope.jp)
