We are investigating a class of young stellar objects with the Spitzer Space Telescope which have falling spectra to 10-15 microns and then rise steeply through the mid-infrared. This type of spectra may be indicative of dust clearing in the inner disk and is thus important to examine closely for signatures of planet formation. One of the best examples in the 'c2d' dataset is LkH-alpha 330 which is a solar analogue in Perseus. This star has not been well studied. We have assembled complementary data from Keck and OVRO to examine other regions of the disk. NIRSPEC data at 4.7 microns clearly shows that there is still CO gas in the inner radii.The IRS coverage of the crucial mid-infrared wavelength range gives exciting insights into the disk structure of this previously unremarkable star.
