Transitional Disk

(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 (forming 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.
