  • τ Ceti is a nearby, mature G-type star very similar to our Sun, with a massive Kuiper Belt analogue and possible multiplanet system that has been compared to our Solar system. We present Herschel Space Observatory images of the debris disc, finding the disc is resolved at 70µm and 160µm, and marginally resolved at 250µm. The Herschel images and infrared photometry from the literature are best modelled using a wide dust annulus with an inner edge between1and10auandanouteredgeat ∼55au… CONTINUE READING
