Scientific paper

Spitzer photometric surveys are currently being conducted for new debris disks in the solar neighborhood. One of these studies, "The SIM/TPF Sample: First Steps in the Comparative Planetology of Neighboring Solar Systems", has detected 70 micron excess from the G0 star HD 48682 (56 Aurigae; d= 17 pc). This detection is particularly significant because it appears to be the first debris disk that has been spatially resolved with Spitzer/MIPS beyond the "Fabulous Four" disks of beta Pic, Fomalhaut, Vega, and epsilon Eridani. We propose 4.8 hours of follow-up Spitzer observations to better resolve the disk, fully characterize its spectral energy distribution, and search for any companion objects. Our goals are to understand the disk density distribution and dust properties, placing this system in context with other nearby stars with dusty debris.
