Title: CO Fundamental Absorption in Edge-on Protoplanetary Disks

Abstract: Edge-on protoplanetary disks represent the best opportunity to study the chemical evolution in the inner disk regions around young stars. In this specialized geometry, the line of sight can pass through large columns of gas close to the star making molecular absorption spectroscopy possible (Lahuis et al. 2006). While a powerful diagnostic tool, disks with such a geometry are rare and a study of more objects is necessary to properly characterize the class. By observing the CO fundamental transition in three edge-on disk sources with Phoenix, we will be looking at the gas component in these disks and will have access to crucial line profile information. These sources are part of our Spitzer Cycle 5 IRS program to study inner disk chemistry.
