We have obtained a Gemini South T-ReCS Q _ { a } -band ( 18.3 \mu m ) image and a Spitzer MIPS SED-mode observation of HD 181327 , an F5/F6V member of the \sim 12 Myr old \beta Pictoris moving group .
We resolve the disk in thermal-emission for the first time and find that the northern arm of the disk is 1.4 \times brighter than the southern arm .
In addition , we detect a broad peak in the combined Spitzer IRS and MIPS spectra at 60 -75 \mu m that may be produced by emission from crystalline water ice .
We model the IRS and MIPS data using a size distribution of amorphous olivine and water ice grains ( dn / da \propto a ^ { -2.25 } with a _ { min } consistent with the minimum blow out size and a _ { max } = 20 \mu m ) located at a distance of 86.3 AU from the central star , as observed in previously published scattered-light images .
Since the photo-desorption lifetime for the icy particles is \sim 1400 yr , significantly less than the estimated \sim 12 Myr age of the system , we hypothesize that we have detected debris that may be steadily replenished by collisions among icy Kuiper belt object-like parent bodies in a newly forming planetary system .
