Planetary Cradles
          Samuel Regandell, Uppsala University

          This work aims towards modelling protostellar gas disks to see if the existance of planets (or planetary embryos) embedded in the disk can produce observable features at the disk surface. For now the modelling is done using a one-dimensional code that includes a treatment of both hydrodynamics and radiative transfer. To describe the vertical structure of the disk it is assumed to be divided into an optically thick ``core'' and a thinner ``atmosphere''. Realisitic physics such as the effect of stellar irradiation on a flared disk and detailed microphysics of the radiative transfer process will be included in the model. The work is currently in its early stages.
