(transition disk)
(disk with inner part cleared)

A transitional disk (or transition disk) is a disk at the site of a presumed protostar with the inner portion clear, leaving a ring. It is taken as an indication of accretion to a planet or the star.

The lifetime of transitional disks is of interest, some finding it to be on the order of a mega-year, others finding a somewhat shorter lifetime.
