Axially Symmetric Radiative Transfer Models of Low Mass Protostars
In this paper we present a modification to the method of Efstathiou and Rowan-Robinson (1989) for the solution of the axially symmetric radiative transfer problem in dust clouds, which is more appropriate for modeling protostellar candidates. In contrast to previous attempts to solve the axisymmetric problem, the method integrates the equation of radiative transfer exactly in the sense that it does not neglect any terms in the equation and treats multiple anisotropic scattering. The results of several computed models are presented showing the dependence of the emergent spectrum on the model parameters and viewing angle. We also present a very good fit to the observed spectrum of IRS5 LI551 and compare it with previous work.
