Abstract (from CDS):

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 fewx10–7 M☉, the average mass-loss in the form of dust is fewx10–8 M☉.yr–1, and the integrated luminosity is log(L/L☉)=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.
