Scientific paper

The spectra of Nova Cas 1995 were observed in 1995, 1996 and 1997 with the 2.16 m telescope, which is located in Xinglon Station of Beijing Astronomical Observatory. The dispersion and resolution of the spectra are about 50 Å/mm and 3.5 Å, respectively. The spectra in 1995 are dominated by the Fe II and H I emissions. The H I and He I emissions are the strongest lines in the spectra in 1996. The nova entered the nebular stage in 1997 when the strong [Fe X], [Fe VII], [O III] emission emerged. The color temperature of the ejected matter is calculated from the continuum. The total mass of the ejected matter is estimated to be about 4.7×10-5Msun. The electron density of the nebula is found to be about 1.46×107cm-3. The He abundance of the ejected matter is calculated from the fluxes of Hβ and He II 4683 Å and is NHe/NH = 0.047.
