The star's heat would drive gas out of the inner disk and prevent the huge gaseous planets from forming there.

The inner disk grew brighter and bluer and was suddenly past.

The outer disk extends out more than twice the distance of the empty inner disk.

This allows a clear view of the inner disk of stars within the dust ring.

Matter in the inner disk is heated to millions of degrees, generating the observed X-rays.

The origin of the inner disk is not clear.

"The direct connection between the disappearance of the inner disk and the jet ejection has never been seen until now."

Somehow, soon after each ejection of hot gas from the inner disk, more matter fills the void, and the process is repeated.

The inner black disk is allowed to move freely within the larger clear plastic shell, which makes the eyes appear to move.

There were no stars to see in this inner disk: no detail at all.
