Abstract

We present a new analysis of existing optical and ultraviolet spectra of the ONeMg nova V1974 Cygni 1992. Using these data and the photoionization code Cloudy, we have determined the physical parameters and elemental abundances for this nova. Many of the previous studies of this nova have made use of incorrect analyses, and hence a new study was required. Our results show that the ejecta are enhanced, relative to solar, in helium, nitrogen, oxygen, neon, magnesium, and iron. Carbon was found to be subsolar. We find an ejected mass of ∼2 × 10-4 M. Our model results fit well with observations taken at IR, radio, submillimeter, and X-ray wavelengths.
