Most stars are born in multiple systems. Theory predicts that star-disk interactions in these systems preferentially strip circumstellar disk material away from the lower-mass companion, such that the ratio of the companion disk radius to orbital separation is set by the orbital parameters of the system. To test those predictions, we present a comparison of disk mass as a function of orbital separation and stellar mass ratio using a new, resolved 880 micron Submillimeter Array (SMA) imaging survey of young multiple star systems in Taurus (for stellar mass ratios > 0.1 and separations > 35 AU). We also highlight some initial results from complementary EVLA radio-wave observations of some of these disk-bearing multiple systems, and comment on how they can be used to quantify how dust coagulation in their disks compares with those around isolated stars.
