      In an effort to simultaneously study the gas and dust components of the disc surrounding the young Herbig Ae star HD 169142, we present far-IR observations obtained with the PACS instrument onboard the Herschel Space ...

      The Herschel GASPS key program is a survey of the gas phase of protoplanetary discs, targeting 240 objects which cover a large range of ages, spectral types, and disc properties. To interpret this large quantity of data ...

R.; Ramsay, S.; Rice, K.; Solano, E.; Walker, H.; White, G. J.; Wright, G. (2010)
      Planets are formed in disks around young stars. With an age of similar to 10 Myr, TW Hya is one of the nearest T Tauri stars that is still surrounded by a relatively massive disk. In addition a large number of molecules ...

    • YSOVAR: Mid-Infrared Variability in NGC 1333 

      Rebull, L. M.; Stauffer, J. R.; Cody, A. M.; Guenther, H. M.; Hillenbrand, L. A.; Poppenhaeger, K.; Wolk, S.
