Abstract

In this paper we present preliminary results on the size distribution of

proto-planetary (``proplyds'') disks in the Trapezium Cluster, as

measured from HST/WFPC2 in the Hα (0.656μm) images.

Direct size measurements of a sample of 134 bright proplyds and 14

silhouettes disks, suggest that the size distribution of circumstellar

disks in the Trapezium cluster is well characterized by a power-law

distribution with an exponent of -2.6 between disk diameters 100-500 AU.
