" Visible and Infrared observations of Inter Planetary Dust "
Masateru ISHIGURO (Seoul National University)
and Munetaka UENO (University of Tokyo)
We are promoting to study the origin of inter-planetary dust particle
by visible and infrared observations. We have been conducting the observation
runs with WIZARD, which is a dedicated instrument developed for visible
observation
of the zodiacal light, ground-based telescopes (CFHT, UH88 and Kiso 1m) for the
survey of cometary dust trails, and IRAC on board SST for thermal emission part
of the dust trails. Studies of the inter-planetary dust particle is now very
important to understand evolution and dissipation of dust disks around a star,
since a dozen of extra-zodiacal dust disks are within our samples.
We will introduce the property of the zodiacal dust as well as the particle in
the dust trails based on our recent results.
