Abstract

We carried out near infrared (1.4–4.2 μm) AO imaging and spectroscopy of two edge-on protoplanetary disks; HK TauB and HV TauC located in Taurus molecular cloud. We found a deep H2O Ice absorption (τ~ 1.1, 1.3) for both disks, which might be attributed to cometary dust in the early stage. The resolved images show gradient of the H-K and K-L′ color in the vertical direction to the disk, which is supposed to be due to the dust extinction in the protoplanetary disks.
