Description We propose to obtain PACS range spectroscopy to measure the amount of water ice and dust evolution in protoplanetary disks located within the ~1-2 Myr old Taurus, Chamaeleon, and Ophiuchus clouds. Theoretical works show that grain growth and dust settling are critical first steps in forming planets and that the ice content of disks plays an influential role in the coagulation process. However, the amount of dust evolution actually experienced by disks and their real ice content is largely unconstrained. To provide a quantitative link between theory and observations we will target 40 disks, many of which show signs of planet formation as inferred from gaps and holes in their dust distribution. We will use irradiated accretion disk models to do a self-consistent analysis of their spectral energy distributions utilizing multi-wavelength data from Spitzer and Herschel. This study will determine the degree of dust evolution experienced by the disks and their ice abundances which can serve as constraints for theoretical models of disk evolution and planet formation.

Mission Description Herschel was launched on 14 May 2009! It is the fourth cornerstone mission in the ESA science programme. With a 3.5 m Cassegrain telescope it is the largest space telescope ever launched. It is performing photometry and spectroscopy in approximately the 55-671 µm range, bridging the gap between earlier infrared space missions and groundbased facilities.
