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