Abstract:
We present a study of the whole sample of the Herbig Ae/Be stars observed
with the spectrometers on board of the Infrared Space Observatory (ISO/ESA).
These objects have been studied not only by means of their
infrared continuum emission but also with respect to all the available
photometric data, collected from the optical region to the radio
wavelengths.
The global spectral energy distributions (SEDs) have been compared with the
results of radiative transfer calculations, that
have been made in the framework of a circumstellar (CS) model.
The results of the selection of the best models allow us to infer on the
relationship between the geometry of the CS matter distribution and the
evolutionary stage of these objects.
