Analytical Solution of the Radiative Transfer Equation in a Thin Dusty Circumstellar Shell
OCA, GEMINI Dept., Grasse, France
The radiative transfer equation can be solved analytically for optically thin shells. The solution leads to a semi-analytical expression of the visibility function, which can be compared to the numerical solution given by the DUSTY code. Best-fit model parameters are given using real measurements of ISO fluxes, ISI and VLTI-MIDI visibilities for 3 late-type stars.
