We propose to obtain new 70 and 160 micron photometric observations of a carefully selected sample of debris systems around sun-like stars identified during the Spitzer Legacy Science Program titled, the Formation and Evolution of Planetary Systems (FEPS). Our proposed Spitzer observations will complete the detailed follow-up characterization of FEPS-identified debris systems that began with our previously approved GO2 program. In GO3 we seek to extend the GO2 program to include the 19 additional debris systems that have been identified in the FEPS survey since its completion after the GO2 deadline. The proposed 70 and 160 micron observations are crucial in order to compare dust from 30 - 100 AU in newly identified debris disk systems with evolutionary models of our own Kuiper Belt. Our ultimate goal, then, is to use these results to assess whether solar systems like our own are common or rare among sun-like stars in the disk of the Milky Way. Our enhanced spectral energy distributions, and the subsequent well constrained accompanying debris disk models, will further the FEPS science legacy by serving as templates for, and be complementary with, existing Spitzer data sets that have been acquired by other GTO and GO surveys of sun-like stars.
