Scientific paper

The authors present optical spectrophotometry and infrared photometry of PW Vul (Nova Vul 1984 No. 1), a slow classical nova. Their analysis suggests that the helium abundance (He/H ≡ 0.12) is slightly below normal for a slow nova, but comparable to that observed in fast novae. The oxygen and neon abundances are close to solar if the electron temperature in the ejecta exceeds 15,000K, but oxygen is enhanced by ≡10 times its solar value if the electron temperature is close to 10,000K.
