    • Radiation feedback on dusty clouds during Seyfert activity 

      Schartmann, M.; Krause, Martin; Burkert, A. (2011-07-21)
      We investigate the evolution of dusty gas clouds falling into the centre of an active Seyfert nucleus. 2D high-resolution radiation hydrodynamics simulations are performed to study the fate of single clouds and the interaction ...
    • Radiation-driven accretion disk winds 

      Drew, J.E.; Proga, D. (2000)
      The concept of an ‘effective' Eddington limit as a lower bound on the system luminosity required for mass loss to be radiation pressure driven is discussed and shown to fall in the interesting regime for high-state ...
    • A radiation-driven disc wind model for massive young stellar objects 

      Drew, J.E.; Proga, D.; Stone, J.M. (1998)
      A radiation-driven disk wind model is proposed that offers great promise of explaining the extreme mass loss signatures of massive young stellar objects (the BN-type objects and more luminous Herbig Be stars). It is argued ...
    • Radiation-driven winds from luminous accretion discs 

      Proga, D.; Stone, J.M.; Drew, J.E. (1998)
      We study the two-dimensional, time-dependent hydrodynamics of radiation-driven winds from luminous accretion disks in which the radiation force is mediated primar- ily by spectral lines. We assume the disk is flat, Keplerian, ...
    • Radiative age mapping of the remnant radio galaxy B2 0924+30 : The LOFAR perspective
