Scientific paper

We propose to complete a medium-scale MIPS 24 and 70 micron census of Sun-like stars in order to identify additional dust systems for detailed follow-up within the Spitzer mission lifetime. Our sample builds upon results from disparate GTO and GO programs to establish a truly volume-limited survey of K,G, and F dwarfs (0.7 msun < M* < 1.7 msun) within 25 pc. To achieve this goal, we add new observations of 660 objects to the current sample of 300 targets in the ROC for a combined volume-limited sample of 960 Sun-like stars. Assuming a 10% detection rate derived from other studies, we expect to discover 65 new disk systems. To provide a lasting resource to the community and for comparison with stellar properties likely to affect disk incidence, we will archive our results into the NStars Database (http://nstars.nau.edu) after publication together with appropriate GTO/GO data when these become publicly available.
