Abstract

The authors report the discovery of near-infrared line emission from high ionization states of aluminum, silicon, calcium, magnesium, and neon within the ejecta shell of Nova Vulpeculae 1984 No. 2. They argue that the observed states are produced by photoionization, and are in ionization equilibrium with a 6×105K low-density plasma which has been greatly enriched in aluminum, neon, and magnesium relative to the Sun. The spatial distribution of the ejecta shell is also discussed.
