Kuiper Belt, Circumstellar Matter, Stars: Individual: Ɛ Eri

Scientific paper

We have searched for the J= 2-1 emission of carbon monoxide (CO) from the brightest peak in the epsilon Eridani (ɛ Eri) dust disc - without success. The non-detection sets 3σ upper limits to the mass of CO gas in the dust peak of 3.3 × 1016 kg and to the total amount of (H2) gas in the disc of 8 × 1019 kg. The paucity of gas in the disc (there is ~1000× more dust) constrains the composition of orbiting comets or icy planetesimals. If these comprise the pre-eminent reservoir of dust and gas in both the Edgeworth-Kuiper Belt (EKB) and the ɛ Eri disc then it seems unlikely that the ɛ Eri planetesimals can be as rich in volatiles as their EKB counterparts.
