Scientific paper

We present results of modelling Herschel PACS and SPIRE observations of three Spitzer-discovered debris discs in the Herschel/DUNES sample. The debris discs presented here have been resolved for the first time at far-infrared wavelengths in the PACS observations, enabling better constraint of the circumstellar dust properties by constraining the dust radial location. We calculate the disc extent of each target to be comparable to that of the Solar System's own cold debris disc, the Edgeworth-Kuiper belt (EKB), around 50- 100 AU in radius and fractional luminosities (LIR/L⋆) in the range 10-6-10-5, comparable to that expected of the EKB.
