A RESOLVED RING OF DEBRIS DUST AROUND THE SOLAR ANALOG HD 107146

We present resolved images of the dust continuum emission from the debris disk around the young (80-200 Myr) solar-type star HD 107146 with CARMA at lambda = 1.3 mm and the CSO at lambda = 350 mu m. Both images show that the dust emission extends over an approximately 10 '' diameter region. The high-resolution (3 '') CARMA image further reveals that the dust is distributed in a partial ring with significant decrease in a flux inward of 97 AU. Two prominent emission peaks appear within the ring separated by similar to 140 degrees in the position angle. The morphology of the dust emission is suggestive of dust captured into a mean motion resonance, which would imply the presence of a planet at an orbital radius of similar to 45-75 AU.
