Abstract:
The shell-like dusty envelope of IRC+10216 has been observed
in several bands with the VLT/FORS1 instrument.
The collected deep and high resolution images have allowed us to
map simultaneously for the first time both the central (inner 10 arcsec)
and the most external
(up to 3 arcmin) regions of the envelope.
From the observed colors and numerical simulations of the nebula,
we plan to derive new
constraints regarding the galactic radiation field illuminating IRC+10216
and the properties of the dust grains found in its envelope.
