A simplified model of radiative transfer is applied here to the infrared object IRC + 10216. It is shown that the flux emitted by this source can be explained by considering the presence of amorphous carbon grains around the central star. The stellar parameters of the model are consistent with the variability phases of the central star, and the values of the geometrical and physical parameters of the envelope, deduced from best fits, are in agreement with those obtained elsewhere.
