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 \sim 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 .
