  The presence of debris disks around young main sequence stars hints at the
existence and structure of planetary systems. Millimeter-wavelength
observations probe large grains that trace the location of planetesimal belts.
The FEPS (Formation and Evolution of Planetary Systems) $Spitzer$ Legacy survey
of nearby young solar analogues yielded a sample of five debris disk-hosting
stars with millimeter flux suitable for interferometric follow-up. We present
observations with the Submillimeter Array (SMA) and the Combined Array for
Research in Millimeter-wave Astronomy (CARMA) at ~2" resolution that spatially
resolve the debris disks around these nearby ($d\sim$50 pc) stars. Two of the
five disks (HD 377, HD 8907) are spatially resolved for the first time and one
(HD 104860) is resolved at millimeter wavelengths for the first time. We
combine our new observations with archival SMA and Atacama Large
Millimeter/Submillimeter Array (ALMA) data to enable a uniform analysis of the
full five-object sample. We simultaneously model the broad-band photometric
data and resolved millimeter visibilities to constrain the dust temperatures
and disk morphologies, and perform an MCMC analysis to fit for basic structural
parameters. We find that the radii and widths of the cold outer belts exhibit
properties consistent with scaled-up versions of the Solar System's Kuiper
Belt. All the disks exhibit characteristic grain sizes comparable to the
blowout size, and all the resolved observations of emission from large dust
grains are consistent with an axisymmetric dust distribution to within the
uncertainties. These results are consistent with comparable studies carried out
at infrared wavelengths.
