Scientific paper

We present a combined analysis of Spitzer and WISE mid-infrared photometry of more than 500 A and B type stars across the Cygnus X massive star forming complex to study the evolution of disk emission around intermediate mass stars. We find SEDs similar to those of Herbig AeBe stars but also many SEDs that suggest the presence of evolved disks with optically thick outer and optically thin or empty inner disks. Following our finding of similar results in the W4 and W5 regions we argue that these are candidates for disks in the process forming Jovian mass objects. We will use the combined results of these studies to constrain the necessary formation timescales of extrasolar planets as a function of stellar mass.
