Spectroscopic Evolution of Nova Vul 1984 No. 1 (PW Vul) and No. 2

Abstract

ABSTRACT. Spectroscopic observations of two novae (Nova Vul 1984 No. 1 and No. 2) have been carried out at the Asiago Observatory from the moment of their discovery up to now. A short preliminary description of the spectral characteristics and evolution of these two novae is reported together with a brief comparison of their properties. The purpose of this paper is that of giving a preliminary description of the characteristics and spectral evolution of the two novae. Detailed data on the available material and final results will be presented in successive papers.
