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.
