GASPS - Herschel survey of FIR lines from Class II through to debris disks Bill Dent The Herschel program GASPS uses PACS to survey a large sample of protoplanetary and debris disks in gas and dust in the FIR. It aims to provide a dataset of spectra from the brightest FIR lines and complete the SEDs of 0.5-30Myr disk-dominated systems. The sample includes up to 200 stars with a wide range of spectral type, accretion, X-ray and UV flux. Targets include T Tauri and Herbig AeBe stars within 200pc. We have surveyed [OI] at 63um (the brightest line in the FIR) together with FIR 60, 110 and 170um fluxes. This is combined with multi-wavelength data and the radiative transfer codes ProDiMo and MCFOST to give self-consistent disk models for wide sample. In addition, the brighter targets were sampled in [CII]157um, [OI]145um, high-J CO and several lines of warm H2O. We discuss possible origin for these lines, include disks and outflows, and how this compares with emission at other wavelengths. Some of the first results are summarized, including the lines detection statistics, and their correlations with system parameters. As well, some detailed models of individual objects are shown.
