Abstrakt

We present a Spitzer study of the pre-main sequence population of the

young cluster NGC 2264. The disk population is divided into three

classes, based on individual spectral energy distributions: optically

thick disks, in a homologous manner depleted or anemic disks, and

radially depleted transition disks. Our analysis indicated that there

may be two distinct evolutionary paths; disks evolve from optically

thick to anemic via the first path, and from optically thick to

transition in the second. Most of the disks seem to follow the first

path. It is yet unknown what physical mechanism triggers this

evolutionary differentiation - it could be directly connected to the

nature of planet formation within the disk.
