[HTML][HTML] A Monte Carlo approach to non-LTE radiative transfer problems
C Bernes�- Astronomy and Astrophysics, vol. 73, no. 1-2, Mar�…, 1979 - adsabs.harvard.edu
A procedure for the solution of non-LTE multilevel radiative-transfer problems using the
Monte Carlo method is developed and shown to be useful. This procedure allows the
inclusion of velocity fields, inhomogeneities, and complex geometries. It is applied to a study
of the transfer of CO line radiation in a model of a spherical collapsing dark cloud. A
technique for reducing the random fluctuations inherent in the Monte Carlo method is
introduced. This technique typically reduces computing times by an order of magnitude in�…
