We propose to use high-resolution spectroscopy to measure the velocity-resolved spatial structure in fundamental CO emission in the inner disks of Herbig Ae/Be stars. As CO is a tracer of the gas in the inner disk, we will constrain the spatial distribution of the circumstellar gas. Measuring the gas distribution in the inner disk can discriminate between multiple formation scenarios that cannot be determined by other means. Further, gas comprises the majority of disk material and is central to circularizing the orbit of terrestrial planets. Thus, studying circumstellar gas is key to our understanding of planet formation and the evolution of circumstellar disks. This study takes advantage of high-resolution afforded by PHOENIX to determine where the CO emitting gas arises, independent of assumptions disk velocity field. This provides an independent measurement of √M_starsin(i), and assuming a simple disk geometry, constrains the inclination of the inner disk as well.
