The Shell of QU Vulpeculae at 2.2 Microns, Hα, and 3.6 Centimeters
Observations of the classical nova QU Vul (1984) were carried out in theinfrared, optical, and radio regimes between days 3791 and 4262 afterdiscovery. For the first time a spatial extension of the shell around QUVul could be unambiguously established from our IR and opticalobservations. At 2.2 mum, a shell size of about 0.8" was found, whichcorresponds to a linear diameter of (4.5 +/- 0.4) x 10^16 cm on day 4124assuming QU Vul is 3.6 kpc distant. The mass of the shell is (4 +/- 1.5)x 10^-4 M_ȯ with the assumption that a free-free emission process isthe dominant emission mechanism in the shell. This shell mass is largerthan found for any nova.
