Radiative transfer in axisymmetric circumstellar dust shells.

LOPEZ B., MEKARNIA D. and LEFEVRE J.

Abstract (from CDS):

A non-spherical dust shell radiative simulation, aiming both at analysing the existing data on evolved stars and at preparing the interpretation of the scheduled high angular resolution imaging, is described. The calculated radiative equilibrium derives from a Monte Carlo method. The exact solution of the transfer is thus computed for different wavelengths.
Result. are obtained for different modellings with peculiar axisymmetric dust density distributions. The broad band spectra, the brigthness distribution of the shell as a fonction of wavelength and view angle and the corresponding visibility maps, display typical observable properties. In a first attempt the spectrum and the visible image of the Red Rectangle are reproduced with a flared disc.
