- Title
ANALYTICAL SOLUTION OF THE RADIATIVE TRANSFER EQUATION IN A THIN DUSTY CIRCUMSTELLAR SHELL.
- Authors
Cruzalèbes, P.; Sacuto, S.
- Abstract
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.
