These stars were selected without regard to their age, metallicity, or any previous detection of IR excess; they have a median age of ∼4 Gyr. We have detected 70 μm excesses around seven stars at the 3 σ confidence level. This extra emission is produced by cool material (< 100 K) located beyond 10 AU, well outside the "habitable zones" of these systems and consistent with the presence of Kuiper Belt analogs with ∼100 times more emitting surface area than in our own planetary system. Only one star, HD 69830, shows excess emission at 24 μm, corresponding to dust with temperatures ≳300 K located inside of 1 AU. While debris disks with Ldust/L* ≥ 10-3 are rare around old FGK stars, we find that the disk frequency increases from 2% ± 2% for L dust/L* ≥ 10-4 to 12% ± 5% for L dust/L* ≥ 10-5. This trend in the disk luminosity distribution is consistent with the estimated dust in our solar system being within an order of magnitude greater or less than the typical level around similar nearby stars. Although there is no correlation of IR excess with metallicity or spectral type, there is a weak correlation with stellar age, with stars younger than a gigayear more likely to have excess emission.
