Title: Multi-Band Mid-Infrared Observation of Saturn's Rings

Abstract:
In this presentation, we present multi-band mid-infrared (MIR) images of Saturn's rings in 2008 
obtained with COMICS mounted on Subaru Telescope. From the images, we measured surface 
brightness of several positions in the rings, and composed spectral energy distributions (SEDs). 
We found that the composed MIR SEDs are fitted fairly well with a single-temperature 
blackbody without dust features. We also present the radial profiles of the surface brightness, 
color, and optical depth in the MIR, and temperature of Saturn’s rings, and discuss their 
characteristics.
