Query: Modeling the Infrared Emission from the Epsilon Eridani Disk   We model the infrared (IR) emission from the ring-like dust disk around the
main-sequence (MS) star Epsilon Eridani, a young analog to our solar system, in
terms of a porous dust model previously developed for the extended wedge-shaped
disk around the MS star $\beta$ Pictoris and the sharply truncated ring-like
disks around the Herbig Ae/Be stars HR 4796A and HD 141569A. It is shown that
the porous dust model with a porosity of $\simali$90% is also successful in
reproducing the IR to submillimeter dust emission spectral energy distribution
as well as the 850$\mum$ flux radial profile of the dust ring around the more
evolved MS star Epsilon Eridani. Predictions are made for future {\it SIRTF}
observations which may allow a direct test of the porous dust model.
