The composition and spatial distribution of molecular gas in the inner few AU of young (< 10 Myr) circumstellar disks are important components to our understanding of the formation and evolution of extrasolar planetary systems. Recent observations of these systems with HST-COS have vastly increased the number of disks with well-characterized ultraviolet H2 and CO spectra, and initial results suggest a CO/H2 ratio 3-to-4 orders of magnitude larger than expected from interstellar abundances. It is not clear from existing observations if this reflects the local CO/H2 abundance ratio or if these observations are sampling separate molecular populations. We propose Project WHIPS (Warm H2 in Protoplanetary Systems) to answer this question by using absorption line spectrosopy of H2 to directly probe a sightline through the warm molecular material in a sample of three disks with well-characterized CO absorption. This program takes advantage of the short-wavelength, medium-resolution capability of the newly commissioned COS G130M lam1222 mode to measure warm H2 absorption in circumstellar disks with Hubble for the first time. We will observe 3 protoplanetary disk targets to directly measure the CO/H2 abundance ratio in at planet-forming radii (r < 10 AU). We will combine CO observations of the 4th Positive Band with observations of the H2 Lyman system. The CO lines have been observed previously as part of HST GO 11616. H2 will be studied with the newly comissioned G130M CENWAVE1222 mode. These targets have all been safely observed previously with HST-COS and STIS and we use these spectra to calculate exposure times and intrument safety.
