Scientific paper

We report the possible detection of V4334 Sgr (Sakurai's Object) at 450 and 850μm with SCUBA on the James Clerk Maxwell Telescope. The submillimetre photometry, combined with a 1-5μm spectrum and 8-10μm photometry obtained nearly contemporaneously, suggests that the submillimetre emission originates in material ejected during the 1995 event. The dust mass is a few×10-7Msolar, the average mass-loss in the form of dust is few×10-8Msolaryr-1, and the integrated luminosity is log(L/Lsolar)=3.66 for a distance of 2kpc. The ejected shell had angular diameter ~55mas in 2001 August, and should by now be resolvable in the mid-infrared by 8-10m class telescopes.
