摘要
We have calculated the circumstellar extinction curves produced by dust grains which absorb and scatter the stellar radiation in the shells of pre-main-sequence stars. A Monte Carlo method was used to model the radiative transfer in non-spherical shells. The dependence on the particle size distribution and the dust shell parameters has been examined. The application of the theoretical results to explain the extinction and polarization of the Herbig Be star ED 45677 shows that the dust shell is not disk-like and that very small grains are absent in it.
