Computing radiative equilibria with Monte Carlo techniques
Received 7 September 1998 / Accepted 9 December 1998
Monte Carlo techniques are used iteratively to compute the radiative equilibrium temperature stratification of a non-grey, spherically-extended stellar atmosphere in LTE. The derived temperature distribution agrees well with that predicted by Castor's (1974) code, as also does the emergent spectrum. However, in contrast to such conventional codes, the adopted Monte Carlo techniques and associated temperature-correction procedure are in no way restricted to 1-D stratifications. Accordingly, this successful test indicates that realistic 2- and 3-D radiative equilibria can be similarly computed.
