Observations at 70 \mu m with the Spitzer Space Telescope have detected several stellar systems within 65 pc of the Sun .
Of 18 presumably young systems detected in this study , as many as 15 have 70 \mu m emission in excess of that expected from their stellar photospheres .
Five of the systems with excesses are members of the Tucanae Association .
The 70 \mu m excesses range from a factor of \sim 2 to nearly 30 times the expected photospheric emission from these stars .
In contrast to the 70 \mu m properties of these systems , there is evidence for an emission excess at 24 \mu m for only HD 3003 , confirming previous results for this star .
The lack of a strong 24 \mu m excess in most of these systems suggests that the circumstellar dust producing the IR excesses is relatively cool ( T _ { dust } \lesssim 150 K ) and that there is little IR-emitting material within the inner few AU of the primary stars .
Many of these systems lie close enough to Earth that the distribution of the dust producing the IR excesses might be imaged in scattered light at optical and near-IR wavelengths .
