irsasupport@ipac.caltech.edu circumstellar disks The Formation and Evolution of Planetary Systems (FEPS) Spitzer Legacy program was designed to characterize the evolution of circumstellar gas and dust around solar-type stars between ages of 3 Myr and 3 Gyr. To achieve these goals, FEPS obtained spectrophotometric observations with the Spitzer Space Telescope for a sample of 328 stars. The observing strategy was to measure the spectral energy distribution (SED) between wavelengths of 3.6 and 70 μm with IRAC and MIPS photometry, and between 8 and 35 μm with low-resolution IRS spectra. In addition, the FEPS program obtained MIPS 160 μm photometry for 80 stars to search for colder dust, and high-resolution IRS spectra for 33 sources to probe for circumstellar gas. https://irsa.ipac.caltech.edu/data/SPITZER/FEPS/overview.html Archive Research 1 https://irsa.ipac.caltech.edu/SSA?COLLECTION=spitzer_feps& minimal survey archival ICRS 47.5512025 14.5998733 0.5 Infrared
