    • Line-driven disc wind models with an improved line force 

      Proga, D.; Stone, J.M.; Drew, J.E. (1999)
      We describe an efficient method of calculating the radiation pressure due to spectral lines, including all the terms in the velocity gradient tensor. We apply this method to calculate the two-dimensional, time-dependent ...

    • 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, ...
