  The inner structure and properties (temperature, mass) of the circumstellar
disk of Herbig star MWC480 are studied by stellar interferometry method used in
the infrared and are interpreted using semi-analytical models. From these
models, the SED (Spectral Energy Distribution) was fitted and multi- wavelength
intensity map of the source were calculated. The intensity map provides the
input for modeling the Keck Interferometer (KI) data in the near-infrared
(near-IR) and the data of the Very Large Telescope Interferometer (VLTI) with
the mid-infrared instrument MIDI. We conclude that with our limited set of
data, we can fit the SED, the Keck visibilities and the MIDI visibilities using
a two-components disk model. Furthermore, we suspect that MWC480 has a
transitional dusty disk. However, we need more MIDI observations with different
baseline orientations to confirm our modeling.
