Overview

The Formation and Evolution of Planetary Systems (FEPS) Spitzer Legacy program was designed to characterize the evolution of circumstellar gas and dust around solartype 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 micron with IRAC and MIPS photometry, and between 8 and 35 micron with low-resolution IRS spectra. In addition, the FEPS program obtained MIPS 160 micron photometry for 80 stars to search for colder dust, and high-resolution IRS spectra for 33 sources to probe for circumstellar gas. If you use FEPS data, please cite Carpenter et al. (2008).
